Hello!
I'm experiencing repeated (1-4 times a week) non-reproductable panics on 4.8-RELEASE-p13. Actually, they have begun with 4.5-RELEASE, and I hoped that upgrade helped me.
Fatal trap 12: page fault while in kernel mode
mp_lock = 00000002; cpuid = 0; lapic.id = 03000000
fault virtual address = 0x6c
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc0273145
stack pointer = 0x10:0xe7e95dc8
frame pointer = 0x10:0xe7e95de8
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 = 77770 (suexec)
interrupt mask = none <- SMP: XXX
trap number = 12
panic: page fault
mp_lock = 00000002; cpuid = 0; lapic.id = 03000000

Panic is ALWAYS in somewhere under Xint0x80_syscall. ALWAYS @Supervisor read"; different programs all the time.
I think it is somethiung hardware-related, but what? The box is a little aged Intel ISP, 2 CPUs, 3 SCSI disks; correlation with disk activity is REALLY slight.
Any ideas, what should I test? I don't get any random sig11.
