next in thread | raw e-mail | index | archive | help
I've been having stability problems in a new dual-core opteron machine.
When it first crashed we were running a number of multicast
applications that were listening to, recording, and rebroadcasting data. I
have been able to re-simulate the data play upto the crash and can
recreate the panic 1 out of every 5 or 6 replays.
the hardware is:
- 2 275 (2.2Ghz) dual-core processors
- tyan 2881 k8sr motherboard (bios 2.05v)
- 2 Gb DDR 400Mhz PC3200 Registered ECC memory
- SEAGATE ST3146807LC scsi drive
- intel dual-port gigabit ethernet card
I have experienced the problem in both 5.4-RELEASE and STABLE (stable
as-of today). I am running a custom SMP kernel.
The most recent panic message was:
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x88
fault code = supervisor read, page not present

Every time it crashes the current process is pagedaemon, and the
instruction pointer points to 'thread_fini'.
