I have the Gateway Solo 5150 laptop computer running kernel 2.2.16 and
pcmcia-cs 3.1.16. Occasionally, when I am xfering data over the
network ( 3COM 575B pcmcia NIC ), the networking services freeze up
quite hard. The only cure is to open up cardmanager and reset the
NIC.
david@solo:> /sbin/lsmod
Module Size Used by
3c575_cb 19948 2
cb_enabler 2280 2 [3c575_cb]
ds 6728 2 [cb_enabler]
i82365 23612 2
pcmcia_core 47680 0 [cb_enabler ds i82365]
Either there is a bug in pcmcia-cs, the driver for the NIC, or the NIC
has a hardware bug. How do I find out which it is? I suppose the bug
could also be in the kernel or NFS.
This problem has existed for all earlier kernels that I have used in
the 2.2.x and 2.0.36 series. I have used earlier versions of
pcmcia-cs as well. In some cases, I used the versions as they came
from SuSE, and others I have been using my own builds. I am currently
running SuSE 6.2 and my own compiled kernel and pcmcia-cs.
The compiler makes no difference either.
This bug has a high probability of occuring when I am listening to
music over the lan. My other machine has a larger HD, so I keep my
mp3 files there, but I occasionally play them on the laptop and listen
with headphones. I use NFS to mount the disks from the other machine.
I have on occasion moved large amounts of data over the network, using
NFS, without problem. This is one of those 'intermitent' bugs.
Any useful suggestions that help track down and kill the culprit will
be gratefully accepted.

I can't see why this would not work if you were only using the UPS to
keep the system up long enough to power down cleanly. Since this could
be automated, you could also eliminate the monitor from the equation,
providing a bit longer of a cushion time till powerdown.
If you were thinking of using this setup to keep the systems up during
an extended power outage, there could be the problem of one UPS
running out of "juice" before the other. Have you considered placing
each system (cpu & drives) on seperate UPS?

Same reason a 12V car battery costs more than a 12V lantern battery.
More amperage = more dollars. Two or even three batteries of lesser
amperage often cost less than a single large battery. The electronics
inside the UPS are a minor fraction of the cost of manufacturing the
device.

Have you tried the -a option?
-a ``auto-size''. Bypass all tape length considerations, and enforce
writing until an end-of-media indication is returned. This fits
best for most modern tape drives. Use of this option is particu-
larly recommended when appending to an existing tape, or using a
tape drive with hardware compression (where you can never be sure
about the compression ratio).

I have seen a 2Gb file size limit on my Sparc-linux (redhat 6.1). The
limit went away with the upgrade to 6.2. My friends tell me that Redhat
snuck in some of the filesystem patches which were still pending for the
2.2 kernel. Bless their souls.
Oh yeah, we verified that 6.2 fixed the probelm on Intel-linux RH6.2
also.

Keyboard was dead, so was the mouse. Couldn't telnet or ftp in (the
sockect connection was established, though). The first crash caused a
complete kernel lockup (no response) and hardware reset was my only
option.
Can netscape cause a complete system crash (no telnet access)? I can
understand netscape killing X (has happened some times to me) but the
kernel?

Good ide, completely forgot that one. This could help. Maybe use less
aggressive timings in the bios (haven't toughed them for several
month, though).

Hmmm, this I would rather avoid as I have about 3.5Gb stuff laying
around (including the rh60 install). If I reduced the extra modules
and disabled NFS export and stuff like that, maybe I could locate the
cause.

Why do you think the reset caused the file system problem and not the
kernel crash? For all I know, the ide driver could have been halted
during disc update.
I just wish that Linux was able to store crash data somewhere on the
disc (or on floppy) when a crash occured.
The log just doesn't mention anything about the crash...

I had no end of problems until I set "plug-n-play=no" in the BIOS setup
(when the computer boots). After that, install went without a hitch and
I'm a happy customer (as long as they put out updates for new kernels).

I have a laptop with the Intel SpeedStep processor that is
supposed to choose between 550 and 700 MHz processor speed depending
upon
whether it is running on ac or battery power.
Linux is only recognizing the processor as 550 MHz but the bios
and MS Windows recognize it as a 700MHz processor. I've checked my bios
settings and tried to force it to high speed but this does not help.
Am I really loosing 150 MHz of speed when I boot to linux or is this
just a bug in the timing program?
Thanks for any advice,

It took me two days to get it to work. I have two drives, one old quantum
bigfoot (hda), and one ATA66 Quantum Fireball KA (hde). My motherboard is
an Abit BE6 with HPT366
Got a new kernel source, got the patch, patched the source, compiled...
all went well, untill the reboot. All the ide channels were correctly
probed etc., but the thing kept crashing when it tried to probe my quantum
fireball KA drive for its specs.
Read and reread all the HOWTO's and newsgroup messages I could find, but
none helped.
After trial and error, I got it to work after I issued the following
command at boot:
ide2=noautotune
(my fireball is on ide2)
Now it works like a charm.
What I find strange is that nobody else has had this problem. Maybe it is
a problem specific to the Quantum fireball KA... but to who know, it
might help you (or somebody else) out.
Good luck!

You create a bootable floppy, copy it to an image file, and us the "-b
imagefile" option to mkisofs to create the CD image. The normal "-d
data" track can contain whatever additional filesystem that you want
the floppy to mount.
There is a package which makes this easy to build a recovery disk.
Look for "Craig's Recovery CD":
http://annex.com/craig/crcd.htm
I've used it, it works. Runs out of RAMdisk. Very handy when you
want to rearrange partitions, or other occasions when you don't want
to have open files on the hard disks. Copying /proc and /dev works
much better when you aren't running using the ones you are trying to
copy.
A CD-RW beats the hell out of trying cram what you need into a
floppy. I've used and liked tomsrtbt for years, but you don't need to
jump through as many hoops when you have 650MB to work with. Keep the
RAMdisk part small, and remember that most directories can be mounted
read-only. Good firewall potential here.
CD's also boot faster than floppies.

Hi
Before reading a warning that came with a piece of low-level format
software I used it on a seagate ultra wide scsi drive. The utility was
for ide drives only. Now every time any significant disk activity
occurs on that drive the system becomes unstable. This controller works
fine with other drives. Have i thoroughly screwed this drive or is
there some way to recover the drive. I suspect that scsi firmware has
been corrupted, but if that were the case I would expect the drive not
to function at all.
Any suggestions ?
