None Not interrupts: either IO ports or memory

Re: Sad System hangs when starting pcmcia service... (Eric Maes)

There are some very detailed instructions for diagnosing system hangs
in the PCMCIA-HOWTO.

The most important thing is to determine exactly when the hang is
happening.  Interrupts are not the problem, because even before you
forced the interrupt setting, the interrupt probe completed fine
(otherwise you would not have seen those system log messages).  The
next event that happens during the startup sequence is the IO port
probe.  After that, if a card is present in the adapter, the memory
probe is done.

So, you need to determine if the lockup depends on whether or not the
Webgear card is in the slot.  If it only happens with the card in the
slot, it is a memory probe failure, and you need to restrict the low
memory window (the 0xc0000-0xfffff window in /etc/pcmcia/config.opts).
If it happens whether or not a card is present, then you need to work
on the IO port windows in the config.opts file.

It is possible the problem would also go away if you recompiled PCMCIA
with "PnP BIOS support" switched on, since that gives better rules for
automatic resource allocation.
