Bug#628444: Also in stable, now
Hi all
I'm running stable (squeeze), with the standard 2.6.32-5 kernel, on a
Lenovo Thinkpad X200 tablet; lspci says
03:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300
and the module is iwlagn, obviously.
The machine has been running squeeze since it was released without any
problems. But in the last few days, I have started having very
frequent problems along the lines described.
May 31 06:12:32 rigel kernel: [ 1029.842353] ADDRCONF(NETDEV_CHANGE):
wlan0: link becomes ready
May 31 06:12:41 rigel kernel: [ 1038.685375] iwlagn 0000:03:00.0:
iwl_tx_agg_start on ra = a0:21:b7:4d:3d:9c tid = 0
May 31 06:14:43 rigel kernel: [ 1161.316130] No probe response from AP
a0:21:b7:4d:3d:9c after 500ms, disconnecting.
May 31 06:14:43 rigel kernel: [ 1161.320094] iwlagn 0000:03:00.0: MAC
is in deep sleep!. CSR_GP_CNTRL = 0xFFFFFFFF
May 31 06:14:43 rigel kernel: [ 1161.320094] iwlagn 0000:03:00.0: MAC

[...]
At this point rmmod/modprobe do nothing at all, and the only solution
is a reboot. This particular one was on wakeup, but frequently it's in
the middle of normal use.
Nothing's changed with the hardware: I did have the keyboard off a few
weeks ago to remove a stuck stylus, but I don't think the timing is
quite right to suggest I unseated the card at that point; also, the
machine dual-boots into Windows, and I see no problems there, though I
use it much less. However, I do keep the system updated, and I seem to
recall that there was a new kernel *and firmware* version a little
while ago as part of the 6.0.5 release. That was on May 12, and my
problems started, according to the logs, after a reboot on May 14! I
post this in the hope that someone might have some insight as a result
of knowing what's changed in the latest stable release. In the
meantime, I am going to try some of the workrounds described in this
thread.
Cheers
Martin
