>Description:
Laptop is a CTX-700E with a TI PCI-1131 PCI-CardBus Bridge and
a Linksys EtherFast 10/100 PC Card (PCMPC100).
Under 4.4-RC, pcic detection causes:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xeb97b
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc00eb87c
stack pointer = 0x10:0xc049fd78
frame pointer = 0x10:0xc049fd78
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 = 0 (swapper)
interrupt mask = net tty bio cam
trap number = 12
panic: page fault
msmith's pir.c produces the following:
