next in thread | raw e-mail | index | archive | help
When I remove my wi pccard (BUFFALO WLI-PCM-S11) the kernel crashes in
100% cases. Kldunload if_wi and APM sleep also make the same panic. I
enabled OLDCARD and hw.pcic.intr_path=1.
After the card is removed (or kldunload or sleep) I get this message
and panic:
wi0: wi_cmd: busy bit won't clear.
wi0: timeout in wi_seek to fc80/0
wi0: timeout in wi_seek to fc80/0
wi0: timeout in wi_seek to fc80/0
Sleeping on "itrmh" with the following non-sleepablelocks held:
exclusive sleep mutex wi0 (network driver) r = 0 (0xc1c48638) locked @ /usr/freebsd/src/sys/dev/wi/if_wi.c:1029
panic: sleeping thread owns a mutex
