I don't know if it was coincidental or a direct result of my posting, but either way, thank you. -- Chris -----Original Message----- From: owner-freebsd-stable@FreeBSD.ORG [mailto:owner-freebsd-stable@FreeBSD.ORG]On Behalf Of Christopher J. Michaels Sent: Saturday, April 01, 2000 4:05 PM To: freebsd-stable@FreeBSD.ORG Subject: Fatal trap 12: page fault while in kernel mode Running 4.0-STABLE cvsupped at 12:00am EST. Gigabyte GA-7XI w/ Athlon 600 proc. I get the following panic on bootup when the umass driver is compiled into the kernel. It panic's at the point where the root file system would usually be mounted. (This is hand typed since it's not getting far enough to generate a dump): Fatal trap 12: page fault while in kernel mode fault virtual address = 0x70 fault code = supervisor read, page not present instruction pointer = 0x8:0xc0145350 stack pointer = 0x10:0xc025f680 frame pointer = 0x10:0xc025f6a8 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 = Idle interrupt mask = net tty bio cam kernel: type 12 trap, code=0 Stopped at tsleep+0x54: cmpl $0,0x70(%ebx) I did compile with -G and also options DDB, but I haven't the slightest idea what to do at th db> prompt that would be useful. I'd like to submit a PR on this but this doesn't feel like enough info, does anyone have any pointers or is this enough information. I am attaching the DMESG and kernel config of successful boot of the same kernel with umass commented out.
