Hello,
My OpenBSD 3.9-stable Box is quite unstable. I don't have physical access to
my box so I can't debug it directly.
I've recompiled a GENERIC kernel with DEBUG support and set ddb.panic to 0
in sysctl.conf so that it's rebooting automaticly. But no kernel dump is
made after a kernel panic. I searched on the web without finding a solution.
Everytime the kernel panic is different.
I tried the -current (and also 3.8). The result is nearly the same: no more
kernel panics but the system freeze but it's still responding to the ping.
As I said before in another mail, this is NOT due to an hardware failure.
Many SAME machines work perfectly. The only difference is the revision of
the bios (vcore updated and Pstate disabled). I want to find the source of
the bug to correct it if I could.
Can you help me on this I'm quite lost.
Thanks a lot,
++ Jerome
Here are 3 differents kernel panics (from dmesg):
