[Bug 594889] [NEW] WiFi Link 6000 Series (rev 35) crashes regularly on N network

Tue Jun 15 23:51:42 UTC 2010

Public bug reported:

I get the following in dmesg:
[10622.059405] iwlagn 0000:02:00.0: iwl_tx_agg_start on ra = 00:22:75:34:c9:75 tid = 0

[15136.698101] Registered led device: iwl-phy2::TX

(the 10622 item is just to show how big a gap there is from the last
message to the point where it crashes.)

Then I rmmod iwlagn and modprobe it:

And it runs for a while longer before dying.

Note that the restarting at 0x2000... string shows up in other bug
reports, but its a generic error handler in the firmware : this isn't
the same as previous bugs solved for older cards in older kernels; so
I'm filing a new bug.

Lenovo x201s, i7 -640m, lucid 64-bit.
