Hardware Error Messages

2023-10-05 Thread Mick Ab
I have a Desktop PC running Debian 11.

A few days ago I found the following error messages on an xterm window
running in the background :-

Can any helpful information be obtained from them or are they high level
pretty meaningless messages ?

Does Debian have any way of trapping low level hardware Error Messages ?


Clock Icon

2023-07-12 Thread Mick Ab
I have a clock icon on my desktop PC which opens on reboot and then remains
on the top right of the screen all the time.

However, for some reason it has moved (not sure how this happened) and is
now in the middle of the screen under my browser windows (so not visible).

I would like to move the clock, but can't seem to move it with my mouse -
none of the buttons when pressed and held down move it and right clicking
doesn't do anything either.

Can anyone help, please ?


Migrating from hard drives to SSDs

2023-07-11 Thread Mick Ab
I am thinking of changing my storage from two 1TB hard drives in a software
RAID 1 configuration to two M.2 Nvme 1 TB SSDs. The two SSDs would be put
into a software RAID 1 configuration. Currently each hard drive contains
both the operating system and user data.

What steps would you recommend to achieve the above result and would those
steps be the quickest way ?

One of the M.2 slots can operate at PCIe 4.0 and PCIe 3.0, while the other
slot can only operate at PCIe 3.0. If they are to be in a RAID 1 array, I
guess that both slots should be operated at PCIe 3.0 speed.

I have two 1 TB 7500 rpm Seagate hard drives (I don't know the model name).
They are in a Debian software RAID 1 array. I do not have any SMART
diagnostics, but the RAID 1 array looks okay judging from a 'cat
/proc/mdstat' output. Also no audible sign of any imminent failure of
either hard drive.

The error messages were of the form :-

  "/dev/mapper/vgpcname-root contains a file system with errors, check
forced.
   Inodes that were a part of a corrupted orphan linked lost found.
   /dev/mapper/vgpcname-root : UNEXPECTED INCONSISTENCY; RUN fsck
manually.(i.e .,
   without -a or -p options). fsck exited with status code 4. The root
   filesystem on /dev/mapper/vgpcname-root requires a manual fsck

There is then a flashing prompt after "(initramfs)".

The following command was thus run :-

sudo fsck -y /dev/mapper/vgpcname-root

The PC could then be rebooted.

The file system is ext4.

Thanks for your reply.

I don't quite understand what you are proposing.

Do you mean the external HDDs would form a new RAID 1 array for the new
motherboard ?

What would happen to the original RAID 1 disks ?


Raid Array and Changing Motherboard

2023-07-02 Thread Mick Ab
I have a software RAID 1 array of two hard drives. Each of the two disks
contains the Debian operating system and user data.

I am thinking of changing the motherboard because of problems that might be
connected to the current motherboard. The new motherboard would be the same
make and model as the current motherboard.

Would I need to recreate the RAID 1 array for the new motherboard I.e.
re-initialise the current RAID 1 disks and repopulate the disks with data
or can I just set up the software RAID on the new motherboard without
affecting the current data on the RAID 1 drives ?


Nvidia GT 710 and Secure Boot

2023-07-02 Thread Mick Ab
I understand that some people have experienced problems with booting a
motherboard with Secure Boot enabled in the BIOS such that they get a blank
screen, can't enter the BIOS and possibly can't boot at all.

This problem seems to be due to having an old graphics card which doesn't
have UEFI firmware, in particular no GOP driver.

I have an Nvidia Geforce GT 710 graphics card, which is an old card and
probably doesn't have the UEFI firmware or GOP driver needed with the
Secure Boot feature.

Is there a way in which the GT 710 can be updated to incorporate the
necessary UEFI firmware and GOP driver ?


RAM

2023-06-12 Thread Mick Ab
I wish to obtain information about the RAM installed on my PC using the
command line. The information needed is :-

Total RAM stored
Number of sticks used and amount of RAM on each stick
Type of RAM e.g. DDR4
Speed of RAM e.g. 3200 MHz
Manufacturer and model number of RAM

I have seen the dmidecode command being used, but the reliability of the
information returned is not reliable.

Is there any command that will reliably give the required RAM information ?


BIOS version

2023-06-08 Thread Mick Ab
Is there a command that can be used to determine the BIOS version being
used on the motherboard.

I have used dmidecode, but at the bottom of the man page for dmidecode
there is :-

"More often than not, information contained in the DMI tables is
inaccurate, incomplete or simply wrong."


Replacing a Motherboard and CPU

2023-06-06 Thread Mick Ab
If I replace a motherboard in a desktop PC with a motherboard of the same
model and manufacturer, do I need to do anything apart from reconnecting
everything and possibly updating the BIOS ?

If, at the same time as replacing the motherboard,  i also replace the CPU
with a CPU of the same model and manufacturer, do I need to do anything
apart from reconnecting everything and possibly updating the BIOS ?


Re: Error Messages

2023-06-04 Thread Mick Ab
Is it possible that the CPU or motherboard could cause the problem ?


Re: Error Messages

2023-06-02 Thread Mick Ab
Thanks for all the replies to the Error Messages.

I don't know how you find which disk is referred to by ata5.

I think dm-0 is a reference to a Raid setup.

Other information about my hardware and rebooting :-

I have two 1 TB hard drives arranged as a RAID 1 array.

The power supply :-

Corsair TXM Gold 550 W 80+ Gold Certified Semi-modular ATX

About 18 months old.

Motherboard BIOS :-

Someone else was checking the BIOS. They said it was a Beta version. I
discovered my RYZEN 5 5600x is the stepping 0
version of the CPU.

Ram :-

I don't know the make of the Ram - someone built the PC for me.

16GB DDR4-3200MHz RAM  (2 x 8GB sticks, I understand

Reboots :-

Subsequent to those error messages, I tried a reboot.

This failed :-

The reboot error says:

  /dev/mapper/vgpiglit-root contains a file system with errors, check
forced.
   Inodes that were a part of a corrupted orphan linked lost found.
   /dev/mapper/vgpiglit-root : UNEXPECTED INCONSISTENCY; RUN fsck
manually.(i.e .,
   without -a or -p options). fsck exited with status code 4. The root
   filesystem on /dev/mapper/vgpiglit-root requires a manual fsck

There is then a flashing prompt after "(initramfs)".

The fsck command was then performed :-

fsck  -y  /dev/mapper/vgpiglit-root

A subsequent reboot worked.

Firefox then had a very lengthy cursor lag, but this was solved by deleting
the places and favicons data in the Firefox profile.

No more error messages yet.

Thanks very much, David, for your help.

Unfortunately it is not possible to log in to the PC from elsewhere.

As to most of your other points, they will have to wait for another similar
freeze.

I was not able to check logs because, subsequent to the freezing, the PC
had to be rebooted due to a mains power cut and the journald system does
not persist across boots.

Frozen mouse and keyboard

2022-06-15 Thread Mick Ab
I have a fairly new desktop PC running Debian 11. Recently there have been
a few occasions when the PC has failed to
be woken up in the morning after being left overnight. The mouse and
keyboard are frozen. Sometimes the monitor appears to be off and on
one occasion it was on.

A hard reboot has been used to reset the PC, but it is not a good idea to
keep doing that.

There is also a worry that if there is a hardware fault, the situation
might get worse over time.

Has anyone any idea as to what may be causing the problem and what would be
the best way to try and solve it ?

I anticipate it might be difficult to solve the problem given that the
fault is intermittent.

Re: Mounting a USB device

2020-11-03 Thread Mick Ab
I have a straightforward need to backup the current system to a portable
drive before getting an up to date Debian distribution installed
on a new machine.

As previously mentioned, system backups have been successfully carried out
on a regular basis for years to an NTFS portable drive in a USB 3 port.

Recently there was a problem with the USB 3 port and it was also found that
the portable drive had become corrupted.

Hence a new NTFS portable drive was bought to do the backups. A backup was
attempted using the new drive in another USB port.
However the manual mount command failed :-

# mount /media/backup
Failed to write lock '/dev/sde1': Resource temporarily unavailable
Error opening '/dev/sde1': Resource temporarily unavailable
Failed to mount '/dev/sde1': Resource temporarily unavailable

The drive was unplugged from the port without a manual unmount being
performed as it was assumed the drive had not been mounted.

Maybe, however, the new drive was automatically mounted by the usbmount
system (to /media/usb0 ?) when it was plugged in.

In any case the drive should have been manually unmounted before it was
unplugged.

The above mount command is exactly the same as the mount command used
whenever the old drive was mounted. The old drive has an entry in
/etc/fstab so the system knew about the mount parameters for the old drive.
However the new drive does not have an entry in /etc/fstab and the system
would surely be confused by the above mount command.

Furthermore, a card reader was then plugged into the port vacated by the
new drive. An SD card was then inserted into the card reader. Normally the
system would then automatically mount the SD card, but
it didn't.

Some days later, another card reader was plugged into that port and the SD
card inserted into the card reader. This time the card was automatically
mounted.

So there are several happenings above which I do not really understand.
This makes me concerned about how to perform
the vital backup needed before a new system can be set up.

The backup itself is performed using a 'tar  -cvpf' type of command.


Re: Mounting a USB device

2020-11-01 Thread Mick Ab
Many thanks for your email, David.

Apologies for any contradictory messages i have posted. My understanding of
the automatic mount of USB devices has been rapidly evolving.

I have now seen that people have had various problems with usbmount over
the years, so I can quite understand why it might not be in the  most
recent Debian distributions.

My plan is to update my distribution very soon, but first I need to do a
backup of the system to a USB portable hard drive (which uses NTFS).

I would like this backup to go as smoothly as possible.

SD card mount problem

2020-10-29 Thread Mick Ab
A Debian system performed a 'lazy' unmount of a portable hard drive when
the drive was unplugged from a USB 2 port.

A card reader was then plugged into the port and an SD card was inserted
into the card reader. Normally the SD card would be automatically mounted,
but this time nothing happened.

Some days later, a new card reader was plugged into the port and the SD
card inserted into the new card reader. This time, the SD card was
automatically mounted.

Can anyone please explain why the above happened.


Re: Mounting a USB device

2020-10-29 Thread Mick Ab
I am fairly convinced that the USB 3 port previously mentioned has a loose
connection.

It also seems to me that a FAT32 device such as a memory stick is
automatically mounted when inserted in a USB port while the system
is running, if such a device is not referenced in /etc/fstab.

What is not clear to me is what happens to an NTFS device such as a
portable drive when it is inserted in a USB port while the system is
running, if the device is not referenced in /etc/fstab.

The following point is observed :-

USB devices referenced in /etc/fstab are automatically mounted when the
system is rebooted, even though their entries include the noauto option
(the devices are already plugged in when a reboot is performed).

What happens to a USB device that is not referenced in /etc/fstab,
when it is plugged into a USB port while the system is running :-

If the filesystem is FAT32 (e.g. a memory stick) will it always be
automatically mounted or will it always have to be manually mounted ?

If the filesystem is NTFS (e.g. a portable hard drive) will it always
be automatically mounted or will it always have to be manually mounted ?

The automount system appears to be usbmount.

Re: Mounting a USB device

2020-10-27 Thread Mick Ab
Thanks for the replies.

It seems to me that the situation is as follows :-

Filesystems in /etc/fstab which have the noauto option are not
automatically mounted at boot time, so if these filesystems are already
plugged into USB ports at boot time, they would subsequently have to be
manually mounted in order to be used.

Filesystems which are plugged into a port after the system has been booted
are automatically mounted.

Mounting a USB device

2020-10-27 Thread Mick Ab
If a filesystem in /etc/fstab has a noauto entry, can that filesystem only
be mounted manually using the mount command or
is there any chance that it will be automatically mounted by
usbmount ?

The filesystem is used in a USB port.


Re: Problem unplugging a USB drive

2020-10-26 Thread Mick Ab
The automatic mount and unmount were performed by the USB mount system.

The stick was newish and hasn't been previously written to.

The stick's filesystem is FAT32, in common with most USB sticks.

The auto mount command included the -tvfat option.

I got the message that you frequently see, so it looks as though the stick
just has a dirty bit.

Why did the kernel automatically mount the stick ?

Usually mounts have to be made manually for this port.

Problem unplugging a USB drive

2020-10-26 Thread Mick Ab
A USB memory stick has been plugged into a USB 3 port for quite a few days.
The stick was left there after it was discovered that the kernel does not
recognise it (e.g. fdisk - l does not show the stick).

It was decided to unplug the stick. Subsequently the command
cat  /var/log/messages was run and the messages revealed that just before
the stick was unplugged, the kernel suddenly found the stick and
automatically mounted it to /media/usb0. While the stick was being
unplugged, the system performed a 'lazy' unmount from /media/usb0.

The stick was later plugged back into the USB 3 port and the dmesg command
issued. The dmesg messages revealed that the stick was probably corrupted
due to the lazy unmount.

My question is :-

Why did the kernel suddenly find the stick and automatically mount it just
before the stick was unplugged ?

What does the above message mean ?

Is it related to Iceweasel hanging ?

There is no problem with the internet connection since another browser

Continuing problem with malfunctioning USB 3 port

2020-08-24 Thread Mick Ab
I am still struggling to solve the problem with the malfunctioning USB 3
port on a desktop running Debian.

I would be very grateful if someone could please give useful answers to the
following questions :-

(1) Can the desktop be safely rebooted, if needed, given the USB 3 problem?

(2) Can the USB 3 problem be fixed in some way or is the port now
permanently unavailable?

(3) If the USB 3 port is unavailable, can the new portable hard drive be
used to do a back-up of the system from the USB 2 port currently occupied
by a card reader or is there any risk the card reader will be messed up
again afterwards ?

 (On a previous occasion, a portable hard drive was plugged into this
USB 2 port in place of the card reader. The system issued a message
indicating the port was busy. The card reader was plugged back into the USB
2 port and it was then found that a card inserted into the card reader
could not be mounted).

Problem with USB 3 port

2020-08-19 Thread Mick Ab
There have been problems recently in trying to use the USB 3 port on a
desktop running Debian.

The kernel doesn't recognise either a new portable hard drive or a new
flash drive when each have, in turn, be plugged into that port. Neither
device shows up with fdisk  -l, lsusb or lsblk commands.

Now the following has been done :-

(1) The new flash drive was unplugged from the port

(2) As root, the following command was run :

dmesg  |  tail

The output was as follows :

[3974120.938338] usb 1-1: new high-speed USB device number 66 using xhci_hcd
[3974126.430777] usb 1-1: new high-speed USB device number 67 using xhci_hcd
[3974131.923271] usb 1-1: new high-speed USB device number 68 using xhci_hcd
[3974137.415713] usb 1-1: new high-speed USB device number 69 using xhci_hcd
[3974142.908184] usb 1-1: new high-speed USB device number 70 using xhci_hcd

The above sequence continued up to device number 75

(3) The flash drive was plugged back into the USB 3 port

(4) After a few seconds the following command was run as root :

dmesg  |  tail  -50

The output was as follows :

[3973945.175272] usb 1-1: new high-speed USB device number 34 using xhci_hcd
[3973950.667736] usb 1-1: new high-speed USB device number 35 using xhci_hcd
[3973956.164234] usb 1-1: new high-speed USB device number 36 using xhci_hcd

[3973978.138108] usb 1-1: new high-speed USB device number 40 using xhci_hcd

The above sequence continued until device number 83

Clearly something is wrong with the port. Can anyone say what is causing
the problem and how it can be fixed.  Thank you.


Kernel doesn't recognises devices on USB 3 port

2020-08-06 Thread Mick Ab
There is a problem with a USB 3 port on a desktop running Debian.

Until recently, a backup of the system had been regularly performed to
a portable hard drive plugged into the USB 3 port. The drive had been kept
permanently plugged into the port and was only mounted when a backup is
required.

Then one day the drive could not be mounted. Instead a message of the type
'can't find UUID=' was received. Use of commands such as lsusb,
fdisk -l, lsblk, blkid showed that the kernel does not recognise the hard
drive. Use of dmesg suggested that the drive itself might have a hardware
problem.

A new portable hard drive and a new flash drive were, in turn, plugged into
the USB 3 port, but fdisk -l, lsblk and lsusb outputs suggest that
neither of these devices are recognised by the kernel when in that port.

Someone suggested that the desktop should be unplugged completely
(I.e. at the mains), left for a few minutes and then rebooted.

However, given the uncertainty of the cause of the problem with the port, I
am reluctant to shut down the desktop and reboot in case the reboot fails.


Buster and motherboard

2020-06-03 Thread Mick Ab
I aim to use the AMD Ryzen 5 3600 as the CPU and the MSI X570-A PRO as the
motherboard
with the stable release of Debian Buster as the operating system.

However i was recently given the following information by an MSI user about
the MSI X570-A PRO :-

 "See the following link :-

https://community.amd.com/servlet/jiveservlet/downloadimage/
2-2975897-167843/MSI_X570-PRO.png. png

As you can see, according to the above link, the BIOS offered by MSI is
still Beta, not the final version of
AGESA 1.0.0.5

AGESA 1.0.0.6 is usually the final version that ends the cycle for every
Ryzen generation so its a reference
(this approach has been so for 1st and 2nd Ryzen generations) offering
stability regardless of using 2000 or
3000 series.

 the BIOS should be flashed to AGESA 1.0.0.6 end of 2018 by the seller
before the computer is bought"

I have further been informed that the X570 board and Ryzen 3000 series came
out about the same time as
the stable release of Buster I.e. July 2019

As mentioned at the beginning of this email, various reports have convinced
me that the Ryzen 5 3600 CPU
will work okay with the stable release of Buster. But the MSI X570-A PRO
motherboard and its BIOS may have
a serious issue with Buster. Indeed the motherboard may fail to boot.

So I am rather concerned about the stability offered by the BIOS on the MSI
X570-A PRO motherboard.


Debian 10.0 works with third generation Ryzen

The above article shows that Debian 10.0 works okay with a third generation
Ryzen CPU.

I understood that there were problems with Buster using  third generation
Ryzen.

Has this problem been overcome by installing AMD firmware ?

Also does the particular BIOS used on the motherboard help to overcome the
problem ?

Hello.

I am seeking to have a desktop PC built with the standard Buster kernel
(4.19) as the operating system.

The CPU proposed for the build is a third generation AMD Ryzen 5.

However it has come to my attention that there is a problem in running the
standard Buster kernel with third generation AMD Ryzen CPUs. First and
second generation CPUs appear to work okay.

Also there may be a problem in running the standard Buster kernel with 9th
generation Intel CPUs.

Does anyone have any info about the above, please ?

I further understand that Buster can be made to work with these CPUs by
using the backported version of Buster,
but I wish to use the standard Buster kernel.
