>Description:

After I built a kernel from sources SUPed on August 28, 1998, my IBM
ThinkPad 365XD panics during boot when a Nokia DTP-2 PCMCIA GSM data
card (a serial device) is present.  This did not happen with a kernel
from the 19980723 i386 binary snapshot.

Relevant boot-time console output and backtrace follows.

>How-To-Repeat:

See above.

>Fix:

Presumably the "align" argument given to pcmcia_io_alloc() at
com_pcmcia.c line 244 should be changed from the constant zero to
something else, but I don't know what.
