>Description:
On my 5.4 box (cvsup'ed and rebuilt last night), when I attempt to drop to single-user mode via 'shutdown now', I get the standard prompt for path of shell or return for /bin/sh. If I press return or begin to type the path of a shell, I immediately get a page fault:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xae
fault code = supervisor read, page not present
instruction pointer = 0x8:0xae
stack pointer = 0x10:0xcbcf2ca4
frame pointer = 0x10:0xcbcf2cc0
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 = 13 (irq1: atkbd0)
trap number = 12
panic: page fault
If I attempt to boot into single-user mode, I get the same "shell path or press return" prompt, but I am unable to enter text at it. It's like the keyboard is not plugged in. Ctrl-Alt-Del does work, however, but results in the *same* page fault as above.
For what it's worth, my dmesg output is as follows:
