1. Kernel panic mounting CD-RW in Mandrake 8.1 (Via c hipset issue?)
I've posted this elsewhere but got no responses, and have information to
which might help...
I installed Mandrake 8.1 on my system that uses an Athlon 1000 in an
Epox 8KTA3 mobo, which uses the VIA KT133A / 686B chipset. It also has an
Acer 4432 ATAPI CD-RW on /hdc and an old Toshiba 4x CDROM on /hdd. Kernel
The CD-RW is set up with SCSI emulation, so there is no /dev/hdc (couldn't
even ls it); there is instead /dev/scd0. When I try to mount the CD-RW, it
sits about 20 seconds and then kernel panic occurs.
Others have told me that VIA chips are buggy. I went to Viahardware.com
and saw a lot of talk about problems with sound cards, but I'm using only
motherboard built-in sound (SB emulation) which works fine.
And the system is very stable in Windows 98. I didn't notice problems in
Red Hat 7.1, and only used Mandrake 8.0 for a short time before switching
to Red Hat, in part because it couldn't play music CDs. (Well, Red Hat
turned out not to be great at it either, so that IDE chain is a bit
suspicious.) Finally, I upgraded the BIOS, which viahardware suggests
helps. No difference.
Nothing's visible in KDE but when I try to mount it from console mode, I
can at least see the last 24 lines of the kernel panic. Here's what it
looks like, mostly, from hand-transcription, with some ellipses of my own:
Unable to handle kernel paging request at virtual address a6b40767
E flags: 00010002
... a bunch of registers I didn't get...
process kapm-idled (pid:4, startpage = c1253000)
call trace: ...
code: c7 80 7c 01 00 00 00 00 07 00 8b 3e 24 85 ff 0f 84 68 01 00
<0>Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing
Now I'm not a kernel guru or anything, just trying to be a user, but it
does seem to involve interrupts, and I don't know what kapm-idled is. Does
all of this mean anything to anyone reading it? Thanks!
