Subject2.4test6 pcmcia troubles
Hi,

My Toshiba laptop doesn't seem to like the pcmcia code in
2.4test6 -- I get the oops which follows this message.
(The rest of the boot log is attached.)

The 2.2 stuff works fine, except that it appears unable
to coax interrupts from my compactflash cards.

2.4test4 didn't oops, but was unable to assign an IRQ to
my network card. cflashs work just fine, though.

test7pre3 oopses earlier in what looks like an unrelated
problem.

Cheers,
Matthew.
