>Description:
Coming from 4.3-STABLE as of May 18th I tried to test 4.4-PRERELEASE
on the above machine. I can reliably crash the box when doing heavy
net I/O, otherwise it runs fine. I replaced the Intel NIC with a 3COM
589D but this didn't help.
It runs stable under Win98 (as stable as Win98 can run :-)).
I have other machines (non laptops) here which run perfectly.
_I_ would assume it is something laptop specific -- might
be related to Warners new pccard code. I have also reconfigured
the BIOS to change/share various interrupt combinations without
success.
I have saved the crashdumps for further examination. As you can see,
the box crashes in whichever process it wants...

>How-To-Repeat:
Not difficult here, e.g., by pulling the crashdumps from the box onto
another machine with ftp :-)
>Fix:
Unknown. I have the dumps for further investigation. I can even
upload them somewhere if needed. I can also do tests if desired.
