PC card RS-232 freezes the computer

PC card RS-232 freezes the computer

[Karel Kulhavy]

Hello

When I insert "2 port RS-232" PC card/PCMCIA/carbus/whatever card
(86x53x6mm with a golden strip with 8 nipples and 2x34 connector) into my
Dell Inspiron 510m notebook with 2.6.16.19, the computer freezes and
continues working when I remove it.

The card label says "2 port RS-232 SUNIX Plug Into A Brand-new World
S/N: CB 0077996 Made in Taiwan"

XMMS before freezing plays last 300ms 3 times again.

dmesg shows
pccard: CardBus card inserted into slot 0
pccard: card ejected from slot 0
MCE: The hardware reports a non fatal, correctable incident occurred on
CPU 0.
Bank 0: b200004000000800

Is the kernel intended to behave this way? If yes, is there a way how
to configure up the kernel so the computer doesn't freeze and the card
can be examined with lspci?

Try enabling CONFIG_ISA. I experienced the same lockup with a PCMCIA 
IDE CDROM drive and it was solved by enabling that one.

MCE means hardware problem. Perhaps kernel could do something to
prevent it, but...
