My kernel always panics when I remove my wi pccard (WLI-PCM-S11).
I am using OLDCARD and enabling hw.pcic.intr_path=1. With NEWCARD no
cards work. I reported this bug 2 weeks ago but even today's kernel
panics in exactly the same way. Anyone experiencing the same problem?
Or just my misconfiguration?
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
