Hi,
I'm trying to find out whether there are any others in the same situation as
me. A friend has a Unisys ELI 4003 (486DX4/100 ISA) PC which always panics
on boot with:
EISA watchdog timer expired, likely hardware failure.
We've discovered that this is (very probably) because this machine implements
XT style floating point error reporting, which uses non-maskable interrupts.
The NMI is handled by isa_nmi() which can't find any ISA problem to report,
but thinks that every EISA problem under the sun has occurred because it
reads 0xff from a non-existent port.
I have code to work around this problem, but I shouldn't introduce nasty
hacks unless it saves enough people.
So, anybody out there with either:
- a WORKING Unisys ELI 4003
- any BROKEN ISA box that reports instant EISA failures,
please let me know.
Thanks,
Stephen.
