Last night the machine rebooted itself and got stuck while
booting due to some kernel panic. Colleagues told me
that there were similiar messages print out onto the console
as the ones above.
Therefore I had to reboot the system. As proposed during boot
I was prompted to do a filesystemcheck manually on /dev/hda6.
/dev/hda is a 1.6 GB Western Digital EIDE disk with patched
firmware. Other mass storage media are connected via SCSI
Adaptec2940:

Quantum Fireball 2GB
Fujitsu 1GB
external SONY CDROM 4x
external HP DDS (DDS2 maybe, don't know now)
external IOMEGA ZIP

After all I fiddled around a bit and tried out some programs
which worked fine until I got the upper message print out on
console. I immediately rebooted the system with no problems.
Afterwards I removed a printjob (initiated from WIN95 via
SAMBA, driving lprng). This job took about 45 megabyte memory
(during all that printing of this special job was reinitiated
and progressed). The person who invoked the printjob told me
about some problems that he had with the server in accepting
his job (/tmp is a link to /var/tmp, /dev/hda6 is mounted on
/var and of 245861 kB size with about 213613 kB free if there
are no printjobs).

Since I've removed this 45 MB job (about six hours ago),
no problems occured and the system is stable so far.

Possible reasons might be - although I'm not certain:

1) I recompiled the kernel (kernel-source-2.0.30-1) myself
and unset some of the hardware flags in make config (workarounds
for some buggy chipsets). I did this because I'm using a
Gigabyte 586 board with Intels HX chipset.

2) The harddisk got corrupted? I consider this, because of the
above described happenings.

3) Something completely different, which I haven't even thought
about.

Do you have any comments?

Here is the output of
~#hdparm /dev/hda

/dev/hda:
multcount = 0 (off)
I/O support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 787/64/63, sectors = 3173184, start = 0

Out system is:

- Debian-1.2.13 with some bo packages (mainly user
packages, no system ones except lprng) installed.

- libc.so.5.4.20
