Hi, the custom kernel, I've built on my home router catched a panic today. I don't have any dump, because swap is encrypted. I've got some information written by hand... I hope it helps a bit. fault virtual address = 0xa fault code = supervisor read, page not present instruction pointer = 0x20:0xc07834 stack pointer = 0x28:0xc39aab50 frame pointer = 0x28:0xc39aab6c code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process = 11 (idle: cpu0) Stopped at md_get_mem+0xf: mov 0x4(%eax),%ebx eax = 0x6 ebx = 0xc0714907 ds = sc_buffer.9247+0xe708 Stack trace: md_get_mem md_get_uint32 md_get_uint32le tc_ticktock hardlock uname -a: FreeBSD epona.local 7.2-RELEASE-p1 FreeBSD 7.2-RELEASE-p1 #1: Wed Jun 10 20:22:30 CEST 2009 root@epona.local:/usr/obj/usr/src/sys/EPONA i386 -- Martin
