Bug#535856: crash in drivers/net/wireless/iwlwifi/iwl-tx.c:1127
Package: linux-image-2.6.30-1-686
Severity: important
Ever since I installed 2.6.30-1-686, I am plagued by crashes in
Intel wireless ( Thinkpad X61 w/ intel 4965 agn ) .
Suddenly the screen goes black, machine does not respond
to keypresses, and there's nothing I can do besides Ctrl+SysRq+S
and a hard reset.
( please note that this report is written from a different machine
because the once which has the problem started crashing so often
I cannot even submit this bug report with it )
Here's what appears in syslog:
