Dear All, unfortunately, one of my mpd5 PPPoE access servers started panicing every few hours. I'm running recent 8.3-STABLE (as of 23th May) with WITNESS, INVARIANTS and DEBUG_MEMGUARD compiled. Unfortunately, I'm unable to catch crashdump. For some reason, it is not saved on dumpdev. The only thing I have is panic string: Fatal trap 9: general protection fault while in kernel mode cpuid = 2; apic id = 02 instruction pointer = 0x20:0xffffffff804b4e2d stack pointer = 0x28:0xffffff8185386560 frame pointer = 0x28:0xffffff81853865d0 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 2832 (mpd5) trap number = 9 According to "objdump -d", the fault address points to prelist_remove(). I tried to replace all of hardware, but it still panics in the same way. I would be really grateful for any hints. dmesg output: http://www.frasunek.com/tmp/dmesg.txt kernel config: http://www.frasunek.com/tmp/kernel.txt
