The workaround: build drm-kmod from ports after that all OK.

This is regression for 12.1-STABLE, for 12.1-RELEASE all OK.
I believe that is somewhat expected because there may be changes to the 
KPI in STABLE that have not been merged to a RELEASE branch yet.  So 
since the packages are built against RELEASE branches you will run into 
issues where you need to build the DRM drivers locally for systems 
running both STABLE and CURRENT.

If i915kms.ko is loaded via kld_list in /etc/rc.conf at boot, the screen
goes blank upon loading the module and does not react any more, powercycle
is required. If I load the the module manually after a successful boot,
the screen goes blank and the system reboots after a while; on reboot
a dump is found and written to /var/crash.

Kernel config is GENERIC with added options WITNESS and WITNESS_SKIPSPIN
CPU is a Celeron 2955U (Haswell class) and the graphics controller

Any suggestions how to proceed from here? Any usefull information that

Did you rebuild the drm-fbsd12.0-kmod after updating your world and

ports/graphics/drm-fbsd12.0-kmod directory, then install this updated

The encryption is performed at a filesystem level (per-dataset).

Fair warning, I don't deal much with Dell, but it's curious that iDrac
lists the device protocol as MI

Device Protocol:  NVMe-MI1.0


MI or the Management Interface is defined by NVMe, but it isn't the
same as a block interface. MI typically uses SMBUS and not PCIe to
communicate with the device. So it's possible that the device is
visible to iDrac via SMBUS but may not be on the PCIe bus for
$reasons. Does iDrac have any tools to interact with the device via
MI?


iDRAC does not allow me to do anything with the drives.
But I booted Linux SystemRescueCd and nvme devices are there visible 
in /dev/

printscreen https://ibb.co/sj22Nwg

So I think the HW is OK, but FreeBSD does not recognize the controller?

might be interesting to see what the dmesg buffer and lspci output for 
this device is under linux.  that should give pointers to how the device 
is being presented to the kernel.

i am running 12-STABLE, with an encrypted zfsroot device.  i've pumped 
about 10gigs through it so far restoring my homedir with no issues, and 
zfs scrub has run without any corrupted blocks detected.


so i don't think it's an issue with this specific m.2 device, perhaps 
there is something odd happening in your local env though that is 
causing this issue to crop up.

Hello John, thank you for your reply.

Yesterday I reinstalled the 12.1 on a VirtualBox virtual machine, did the
same steps and it didn't corrupted the ZFS, so I think that the problem is
in the FreeBSD's driver for m.2 SSD.
Besides the corruption of the filesystem, I forgot to mention that I
noticed a little noise on disk writes on FreeBSD, but not on Linux or
Windows.
I found some old threads about incorrectly params for sector size for
Samsung's SSD, but nothing about WD.
If someone responsible for the driver need help to solve this problem, I
can reinstall the FreeBSD on my machine and compile a custom kernel to
gather debug information.


Unfortunately you haven't provided much in details regarding the 
hardware you are running as far as FreeBSD see's it.  I can confirm I 
have had many systems using m.2 for quite a while and have had zero 
issues.  Could you provide some of these details?


(assuming this is an NVMe device):
$ sudo nvmecontrol  devlist
$ sudo pciconf -lv nvme0

if your device isn't NVMe and is a sata device then this info may be 
helpful as well:

$ sudo camcontrol devlist

and your dmesg will also probably be helpful here as well.  I think 
getting at least this basic info will help determine where the issue is 
cropping up.

might want to take a look at sysutils/intel-pcm

on PCIe bus utilization among other useful status.


Also, lookup the bandwidth for the PCIe bus and see if your aggregate 
disk throughput on one of the PCIe lanes is saturating the bus (pcm 
should also help here).  You can also run "zpool iostat -v 2" to see per 
disk i/o metrics to help determine if this is an issue.




BTW i'm sure this has been asked a million times but what would be
some decent benchmark tests while i'm at it?


I generally run several tests and then compare results, for example 
bonnie++, iozone, iperf (writing over the wire and to disk) as well as 
some more realistic scripts based on the use-case i'm building a 
solution for.  hope that helps.

So I found the Partaker on amazon.uk, but they ship from China, and I fear

but I was looking for a more strong CPU and more memory capacity.

The box will be a small lan server, running zfs for 10TB and will be next
firewall machine (when zfs will not be running on it).

The link for this box is

The cpu has 15W TDP and really low power need. It fits just my need. There
is the Protectli on USA (amazon.com), but I can't find it on EU stores.
They look to much alike, so I guess they are brothers separated early on

If anyone could tell me stores and brands that I can order online from

Hi.

First of all, thanks for the detailed instructions. Response inline.



sure thing!


-- pay special attention to the update the /boot/loader.conf


Are you referring to the need to set 'hw.sysconf.disable=1', or is 
there something else I'm missing? I didn't see anything else on the 
wiki page, except for some debugging options (which I guess I'm going 
to end up using soon).


yes that is what i was referring to.  I do not have an AMDGPU system 
myself but have been told several times that it is required.




- after you have configured the amdgpu.ko to load on boot verify
it is

good.  if
you have issues loading the kernel module let us know, there are some
things you can try to setup to get a useful backtrace that will
help us
debug this.


This is where I get to. I've removed amdgpu from /etc/rc.conf, so I 
don't have to boot single-user mode; when I run kldload amdgpu, the 
following happens:


1: the 'kldload amdgpu' process doesn't return immediately, yet the 
terminal is responsive; I can hit return, and have the cursor move. 
The mouse pointer also moves.
2: something around 5s later, the screen turns off, the keyboard goes 
unresponsive (caps lock light doesn't toggle), and the machine no 
longer responds to pings.




interesting, it looks like the kernel module and firmware modules do 
load.  one thing you may want to test is setting the 
"debug.debugger_on_panic=0" sysctl knob before loading the amdgpu.ko.  
hopefully this will allow you to get into a debugger before the system 
locks up.

Hi.

I recently got a Ryzen 2400G, which has on-board AMD Vega 11 graphics. I
can get a console to display via the motherboard's on-board HDMI, but
haven't been able to get Xorg working yet. I'm trying the 'amdgpu' driver,
and am using an xorg.conf file generated with 'Xorg -configure' (albeit
hand-tweaked to get rid of the nonexistent second screen it added, and fix
a few more things).

My understanding is that the driver is likely borrowed from linux, and
(from http://forum.mxlinux.org/viewtopic.php?t=46887) Vega support only
started working with linux kernel 1.19. The /var/log/Xorg.0.log file says
that the amdgpu module was 'compiled for 1.18.4, module version = 18.1.0'.
Does the 1.18.4 refer to a linux kernel version? If so, what's my best
solution here? Should I just wait until the FreeBSD drivers are updated? Is
there anything I can do in the meantime?


I believe there may be some previous success running Vega graphics on 
FreeBSD.  Couple things to note:


- If possible run 12.0-RELEASE
- install the drm-kmod package, then closely follow the instructions 
printed on your console.  This wiki section should offer some help:

https://wiki.freebsd.org/Graphics#AMD_Graphics
-- pay special attention to the update the /boot/loader.conf

- after you have configured the amdgpu.ko to load on boot verify it is 
able to load the kernel module and your console display looks good.  if 
you have issues loading the kernel module let us know, there are some 
things you can try to setup to get a useful backtrace that will help us 
debug this.


- try moving your Xorg.conf out of the way then try starting X.
-- If that fails try dropping your custom config in there which is using 
the amdgpu Xorg driver.



Hope this helps!

$ grep webca /etc/rc.conf
webcamd_enable="YES"

i also load cuse via /boot/loader.conf:
$ sudo grep cuse /boot/loader.conf

Hello,

I’m looking for advice on doing a release upgrade of a running instance.  It 
looks like the normal procedure using freebsd-update requires a reboot between

the install commands back to back without rebooting?  Or is the only safe 
procedure to build a new instance from scratch for each release?
I've done it successfully in the past but IIRC it was pretty sketchy - i 
think i put script in /etc/rc.local to finish the upgrade.


for dev purposes i've done upgrades via rebuilding from source without 
too much drama.  i'd due to the build/mergemasters and installworld 
before a reboot.  but again this was for dev/testing, so if things 
didn't work out loosing data was a non-issue.


I've since decided that one of the advantages of AWS is that I can 
easily just allocate a new VM, but this is predicated that I've got all 
my configs in a config mgmt engine and my user volumes exist on an EBS 
volume.

if you read the full release announcement you will see the following:

yet to be released for 10.4-RELEASE.  As such, this EN does not apply for

Thats actually relly helpdful, thanks! - I dont see a modesetting

it's from the xorg-server port/pkg:

/usr/local/man/man4/modesetting.4.gz

that's not good - if you feel like trying to debug that issue you can 
set the following sysctl knobs which should generate and save a corefile 
when it panic's:


set this in sysctl.conf:
|debug.debugger_on_panic=0|

|and add this to /boot/loader.conf:|
|dev.drm.skip_ddb="1"

then, if you have dumpdev defined like so in rc.conf it should save a 
core in /var/crash:

dumpdev="AUTO"

this sounds like a regression if things were working with a previous 
build but i reckon we'll need more info to help debug.

Even though I don't need the whole xorg.conf, I need xorg.conf.d

does the modesetting driver work when you remove the xorg.conf? (might

Hey there - thanks for testing!  I would recommend posting an issue on
the Github repo for this.  If you could be sure to include which
revision you are running (11-stable or 12-current revision) in addition
to the version of the port/pkg you have install that'd be helpful.

the issue you are seeing is most likely not related to the LOR from the 
original email and PR I filed.  This looks like a media error with the 
disk device on your RAID controller.  A quick google search turn's up 
quite a few threads on this - ranging from bad RAID/JBOD controllers to 
out of date firmware.

Re: No more torrents.....

[pete wright]

 A hybrid of bnbt, xbnbt, xbtt, and something else that I don't recall
 the name of.  We ran the seeders from py-bittornado in curses mode in
 about 15 screen sessions.. by hand.

 The tracker/indexer code had an open http connect proxy in it (!).
 The code was particularly difficult to work with and looked extremely
 light for defensive programming.  (string buffer overflows, the
 works).

 The bottom line is the nice indexer / tracker / stats thing we had
 isn't something I feel we can trust.

 I do believe we can/should publish trackerless/dht torrent files to go
 with the release binaries.

 Perhaps an initial web-seed might work, otherwise we could have a few
 folks with good ftp connectivity do an initial seed from the ftp
 files.


I would be very much be willing to assist with seeding if we make dht
torrent files available from my nodes located in downtown Los Angeles
for west-coast and APAC network presence.

as an aside:
I have been running libtorrent/rtorrent for a bit and it seems like a
pretty decent platform for building on.  having said that - I am not a
security researcher and would be keen to hear if libtorrent/rotrrent
suffers from these similar issues?

 Oh wait, I told a lie.  It wasn't py-bittornado we used.. it was
 rtorrent.  Thanks for prompting that.

 I have no concerns with rtorrent except that it was a curses beastie.
 It was something we had to manually start up after a machine reboot
 until we did some evil scripts with screen.


ah ok - understood.  well i'll keep an eye on the lists, and if some

 Hi, I only flipped through the messages in this thread, faintly remembering

 the transfer rate is much less than what you'd expect - due to the

FWIW I think the general issue for the ssh suite of tools is the
compiled in window size is not tuned for large transfers like this:
http://www.psc.edu/networking/projects/hpn-ssh/theory.php

we use a propritary tool called aspera to overcome these issues when
moving large amounts of data b/w remote sites on our WAN:
http://www.asperasoft.com/products/scp/index.html

the encrytp/decrypt overhead should be pretty minimal on modern
hardware, so i would not expect that to be the first bottle neck you

6.2-RELEASE is the latest stable branch.  you should be able to
upgrade your world to this release with little problems.  going from
6.2-RELEASE to 6.3-RELEASE should be trivial, and any gotcha's should
be documented in /usr/src/UPDATE.  the latest patch level of
6.2-RELEASE should include all security updates, and bug fixes (as

i do not think snapshot's have gone through the same amount of
regression testing as official releases, so you may not want to use
those in production environments.

Re: iscsi and geom mirror - stupid idea or not ?

[pete wright]

On 4/19/07, Pete French [EMAIL PROTECTED] wrote:

what would happen if I made a machine which contained a mirrored
geom pair consiting of one local driive and one drive accessed via iscsi on
a remote machine ? would this work ?

what I am considering is two such machines, geographicly distinct. one is
a 'master' and boots off the mirrored drive, the other is a slave and
has a separate boot drive which just rngs FreeBSD to make the drive inside
it into an iscsi target for the first machine. The idea here is if the first
machine is catastrphicly killed (like building falls down on it or
something) then the second one can be rebooted from the internal drive, and
will hence become the first one. It's basically a way of making a standby
machine in case of disaster.

I havent really looked at iSCSI until recently, and this is just one of
the ideas I came up with looking at the possibilities.



iSCSI is good for many things - although i would not suggest this
setup.  it sounds like you are trying to use the mirror/iSCSI
architecture as some sort of backup scheme.  it may make more sense to
capture snapshot's of your data and mirror that off to secondary
storage.

along these same lines is a common iSCSI implementation of having a
dedicated piece of hardware that manages RAID, grouping of LUN's and
other management functions.  this allows you physically, and
logically, implement some sort of redundancy/backup schema independent
of the iSCSI consumer (i.e. the OS that will be mounting the iSCSI
volume).  let the machine hosting the iSCSI storage do it's job, and
let the client do it's job - it does not make sense to try to mix
these too.

so the short answer is i would not try to mix iSCSI volumes with local
volumes via a software mirror.  a properly implemented iSCSI solution
can easily account for DR situations, and using filesystem
snapshotting will make this task easier as well.

are you sure you are able to write to /tmp, this error looks like it

I printed the full commands that returns the error, it is:

ngctl msg setprogram { thisHook= ifMatch= ifNotMatch=

  What on earth is that all about? The slow box has the ACPI-fast
  timecounter...
 
  Could be ACPI bugs on your system:
 
  Yes, but the other system is 100% equal - hardware, bios config,
  bios and
  bootblock revision, controller bioses, etc. etc.
  It all matches.
 
  Clearly they're not 100% equal, but (100-epsilon)%.  Your job is to
  identify the origin of the epsilon :-)
 
  Yea yea ;) Working on it..
  Is there a way to force ACPI-safe on the slower system?
 
  I think someone already mentioned this..see the
  kern.timecounter.hardware and other kern.timecounter sysctls.

 I have now forced ACPI-safe on the slow system, to match the fast one.
 Too bad though, it made absolutely zero difference.

 I'm upgrading BIOSes on both boxes now, even though they seem equal.
 Then I'll see what ACPI debug output shows me. If you have any other
 hints or ideas, please let me know...  thanks so far.

Have you tired turning off ACPI at boot time.  Is there an option to
turn it off in the BIOS.  This is an HP box correct?  I have had some
fun in the past chasing down hard to reproduce ACPI problems on HP
hardware before, after much software trouble shooting I realized that
by turning some knob's in the BIOS got the machines to a stable state
(in my case I turned off USB auto detection).

  Let us have a look at /etc/make.conf. BTW, my *personal* opinion is AMD
  implements much better pipelining and concurrent processing compared to
  the Intel platform. So what you see is not something entirely unexpected.

 No /etc/make.conf in either case

Are you using the same disks, and disk controllers on each machine?   
building work+kernel does a fair amount of disk I/O, so that would be
one thing to investigate.

Re: Strange SATA problem - data corrupting

 Hello,
 
 I have very strange problem with my FreeBSD box and Promise PDC20579
 SATA controller:
 
 [EMAIL PROTECTED]:7:0: class=0x010400 card=0x3574105a chip=0x3574105a
 rev=0x02 hdr=0x00
 vendor = 'Promise Technology Inc'

 class = mass storage
 subclass = RAID
 
 ad4: 381554MB ST3400832AS/3.02 [775221/16/63] at ata2-master SATA150
 
 Problem is, that every HDD connected to this controller is corrupting
 data. For example: I copy good tar.gz archive to this drive, and if I do
 decompression immediately after copying, there is no problem, but if I
 wait for example 10 minutes, then decompression ends with CRC error:
 
 box# gzip -d ./2005-09-11.tar.gz
 gzip: ./2005-09-11.tar.gz: invalid compressed data--crc error
 gzip: ./2005-09-11.tar.gz: invalid compressed data--length error
 
 I know, that problem is not in HDD or CPU/RAM, but in controller. Could
 it be a driver problem or not? I tried to turn off soft-updates, but
 with no change. I have no any ideas what to do or what to try.
 
 Thanks a lot for any answer or opinion.



Are you sure that it is not an issue with the drives? Just to make sure, you 
have attached these drives to another, known working system and seen the 
same issues. Also, have you made sure that the cabling to the drives 
themselves are not broken, and are seated properlly. To be sure, I'd grab a 
set of working sata cables and test out again. Finally, if you have done 
this hardware trouble shooting already and are sure that it is not a 
hardware issue with your disks/cabling/controller itself I would post the 
version of FreeBSD you are running (uname -ar) along with a dmesg to the 
list.

Re: Need really cheap IDE mirroring PCI controlled for FreebBSD 4.10

 Can anybody recommend cheap IDE mirroring PCI (2.0, not 2.1 or 2.2)
 controller with just 2 IDE ports which works fine with FreeBSD 4.10 ?
 
 It is to be installed on a very old motherboard (1998) and two 40GB IDE
 driver (more or less modern ones, at least not used ones for  sure).

sorry I don't know of any really cheap one's off hand, altho I do have
experience with 3Ware RAID cards on 4.x.  They seemed to work well,
and they are less expensive than proper SCSI cards...altho slower.  If
cost really an issue would it be worth mirroring your disks in
software via VINUM?
