Hi
Whilst running 5.3-RELEASE-p22 on a GENERIC+ SMP options kernel we have had
this:
Fatal trap 12: page fault while in kernel mode
cpuid = 1; apic id = 00
fault virtual address = 0x42d38cf0
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc062f242
stack pointer = 0x10:0xeb4649bc
frame pointer = 0x10:0xeb4649c4
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 1015 (screen)
trap number = 12
panic: page fault
cpuid = 1

It is the 2nd time in a month the server has crashed the first time it
rebooted on its own
so I didn't get the error, but this time I had to power cycle it.
The server is a Dual 800MHz intel box with 1.5GB RAM and 4*36GB RAID SCSI disks,
It generally is not under much load.
Whats the best thing todo? debugging kernel etc or just upgrade to 5.4?
Thanks
Ogg
