Red Hat Bugzilla – Bug 10018
General unreliability and kernel panics on Ultra2 Creator system
Last modified: 2008-05-01 11:37:54 EDT
Hardware: Sun Ultra2 Creator 300 Mhz UltraSparc 384 MB RAM Creator videocard 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 <smiley face> swapper(0): Oops TSTATE: <registers> 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). Good luck, Adam Keys
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 output: sunlance.c:v1.12 11/Mar/99 Miguel de Icaza (miguel@nuclecu.unam.mx) 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.
