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 boot() called on cpu#0 (kgdb) where #0 0xc017f142 in dumpsys () #1 0xc017ef13 in boot () #2 0xc017f36c in poweroff_wait () #3 0xc0274830 in trap_fatal () #4 0xc02744c1 in trap_pfault () #5 0xc027405f in trap () #6 0xc0273145 in setlock () #7 0xc3a222ba in ??

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. -- Alex.
