It stayed up and things were locked up. I haven't been able to analyse it yet, I dumped process stacks a few times and put the resulting log at http://johannes.sipsolutions.net/files/mac80211-bcm43xx-deadlock Note that many processes are in rtnl_lock() but wpa_supplicant is stuck in wait_for_completion. johannes --=-lFL96FX9ey2uws9reFUy Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iD8DBQBGgNV8/ETPhpq3jKURAuhFAKC4KST8h8r1BpqkoO/WRp7OlJFPqQCghVl3 yt/e6GQ2d0Xsa1kxPso28FI= =v0mS -----END PGP SIGNATURE----- --=-lFL96FX9ey2uws9reFUy--
