Serial console log from 2.6.3-rc2

The problem has apparently reappeared in the 2.6.3-rc2.  Attached is a related
log (this time the call trace should be complete :-)).

syslog while loading modules (ieee1394,ohci1394,sbp2) with attached cardbus card(via yenta_socket)

after loading modules, i am unable to unload/list modules. the bug also
appears, when i'm loading these modules without the card inserted. the bug is
new since the 2.6.2-rc kernels. other cards are working properly.

test system: pIII-m/pcmcia(yenta)/noname 1394 card
test kernels(bug related): vanilla-2.6.2/3-rc1/3-rc2 and
2.6.2-mm1/.3-rc1-mm1/.3-rc2-mm1
gcc/libc: 3.3.2 20040119/2.3.3

Comment 4 Rafael J. Wysocki 2004-02-16 01:31:48 UTC

The problem seems to be fixed in the 2.6.3-rc3 kernel.

Comment 5 Ben Collins 2004-03-11 04:46:49 UTC

Pretty sure this is fixed now.
