Red Hat Bugzilla – Bug 10018
General unreliability and kernel panics on Ultra2 Creator system
Last modified: 2008-05-01 11:37:54 EDT
Sun Ultra2 Creator
300 Mhz UltraSparc
384 MB RAM
2 4 gig SCSI drives
hardware raid5 controller?
128 mb swap
The installation process goes smoothly enough. I am using the default
GNOME workstation setup, enabling RAID0 and a network card. I have not
yet experienced a crash during setup. Once the setup is complete, the
machine reboots. The machine lasts for anywhere between 1-30 minutes
after this reboot. Several times I have gotten a kernel panic. Programs
such as linuxconf and PAM have segfaulted, even less(1) or ping(1).
The kernel panic error looks like this:
Unable to handle kernel NULL pointer dereference
tsk->mm->context = <zeros>
tsk->mm->pgd = ffff8000000ec00
Aieee, killing interrupt handler
Kernel panic: Attempted to kill the idle task!
In swapper task - not syncing
The kernel is the default for Redhat 6.1 (2.2.12-something I beleive).
Does this still occur with the 6.2 kernels ?
No reply, so hopefully not. If so - reopen this
As it turns out, the machine has two ethernet interfaces. The first (eth0) is
built part of the SCSI controller. It is a Sunlance, and this is the kernel
sunlance.c:v1.12 11/Mar/99 Miguel de Icaza (email@example.com)
eth0: LANCE 08:00:20:8a:3d:31
Using the other ethernet interface (eth1) has been rock solid however. I can't
find the output in /var/log/dmesg, but I know the sucker is there.
I have not had a chance to test this with the newer kernel.
