Kernel oops when inserting a pcmcia card (2.6.0-test11)

Kernel oops when inserting a pcmcia card (2.6.0-test11)

[Uwe Steinmann]

Hi,

I find myself in xmon as soon as I insert a pcmcia card into
my Pismo PowerBook. I suspect the memory range which is
working for 2.4.21.
Here is what I found in syslog.

I don't have my Pismo here right now but from notes I belive these are
the correct memory ranges (in /etc/pcmcia/config.opts).

include port 0x1000-0x1fff
include memory 0x90000000-0x9003ffff

Comment out other values (from pcmcia-cs) ..

More information can be found here:

I'm using 2.2.21-benX also and pcmcia does work (tested with Orinoco and
SCSI cards).

best
