Greetings -
Excuse any incorrectness, I'm a linux novice/kernel panic newbie.
I have a default Redhat installation of 6.0 on an SMP machine. I has
paniced 2 times in 24 hours on me (its only bee up 24 hours), once while
idle once while I left it doing a continuous ping overnight. The
information I have is from the panic that occured while the system was
doing the ping. I have added no new software to it, just what I picked
from the Redhat installation . The system is only running apache and
syslog for daemons. I have tried to capture what I could from the panic
and from reading the kernel README file. Here goes:
My computer:
Gigabyte GA-6XBD Motherbaord (latest bios)
Dual PII400s (matched stepping, validated on the CPU's and from the boot
logs)
Adaptec 2940UW SCSI Card
Intel Pro100+ NIC
Generic IDE CDROM
Trident 1mg Video Card
Kernel 2.2.5 (redhat)
Attached is my hand created panic screen. I hand wrote the info down
and then typed it in so I hope I got it all correct. Is there a beter
way to capture the panic screen? It's not going to my logs and the
system is hung (duh) when it panics.
The command that dumped was scheduler (determined form the EIP address
in the panic info and using nm vmlinux |sort | less) and I found the
exact instruction using a dissasemble of the scheduler command. The
instruction is cmpl at address c0112437.
Please conact me with any further questions. I will be taking this up
with Redhat as well but who knows if they will be of any help.
Regards,
Scott Tyson
