As a followup, I downloaded the 2.2.0-pre9 kernel, ran the same tests as
before and had the same results, including the panics. The panics were
again in the same function:
701ccd98 t BusLogic_ScanIncomingMailboxes
Any ideas or things that I should try?
I'm fairly certain that it is the virtual to physical mapping macros that are
producing incorrect results. Please try changing linux/include/asm-i386/io.h
from:
#define __io_virt(x) ((void *)(PAGE_OFFSET | (unsigned long)(x)))
#define __io_phys(x) ((unsigned long)(x) & ~PAGE_OFFSET)
to:
#define __io_virt(x) ((void *)((unsigned long)(x) + PAGE_OFFSET))
#define __io_phys(x) ((unsigned long)(x) - PAGE_OFFSET)
and see if that helps.
