Hello.
I'd like to apologize in advance, if I shouldn't report such issues to
this mailing list. I was told this is a good place for bug reports
associated with Linux kernel modules for wireless devices.
I have a ThinkPad X201 Tablet, which I recently bought used. This laptop
has an Intel Centrino Ultimate-N 6300 wireless 802.11abgn card, which is
supported via the iwlwifi module and a firmware image. I'm using Arch
Linux on it (i haven't tried a different OS yet), and so have fairly
recent and vanilla kernel and firmware packages (the policy of this
distribution is to have the latest packages marked as stable by upstream
and only do patching if it's required to build the package or make it
work with others).
Since some time I've been struggling with my laptop's wifi card randomly
locking up (at least, I think the hardware locks up), usually after at
least a few hours of usage. The initial symptom of such an event is the
wifi card ceasing to work. Afterwards, each few seconds the computer
"freezes" for a few other seconds. I can stop these freezes by flipping
a radio disable switch, which causes rfkill's hard block on all wireless
devices. However, flipping it back to unblock doesn't cause the wifi
card to function, only bringing back aforementioned freezes.
These lock-ups happen completely randomly. I'm using this laptop a lot,
over 10 hours daily, and there are days when there is no problem. I even
managed to use it a week without problems. Other times it can happen as
much as 4 times daily. Twice it happened straight after boot, but
otherwise it happens after at least a few hours of usage.
I at first thought, that it might be associated with the amount of data
sent in and out of the interface, but there was no correlation. I
specially tested this by moving large amounts of data within my local
network for a few hours. Next thing I considered, was that the device
overheats due to radiation (I'm usually very close to my AP, and have
the default tx-power setting, which is 15dBm). But these issues happened
no matter how far I was and changing tx-power to smallest possible value
didn't help. I also thought this might be because the device accumulates
heat after a few hours, but recently I got the lock-up 3 minutes after
boot, which happened after the laptop was laying all night powered off.
Since this issues started, I've considered many packages (such as those
network-related and kernel modules like tp-smapi) as the culprits
(especially those installed or updated around the time of the first
occurrence) and tried uninstalling or downgrading. I also tried removing
any module options and udev rules I made before the lock-ups started.
Again, no success.
Finally, I recently tried a few options of the iwlwifi module
(11n_disable=1, swcrypto=1, bt_coex_active=0). None of those helped,
though after setting bt_coex_active=0 I had 2 days of peace. I haven't
tried the power-saving ones yet, though.
My only remaining clue is that this seems more likely to happen if I'm
on battery power, especially when the battery has little charge. So I
guess this might be associated with power management.
I have to say, I don't have the knowledge to understand what's really
going on, how to read the ring buffer output or how to debug such an
issue. But it seems to me, looking at the dmesg output, that the driver
has some issue, the device is reinitialized, which fails. Hence why I
wrote that the device locks up.
I've attached output of dmesg captured right after a recent lock-up. I
hope I have a recent enough kernel for this to be useful. I also
attached outputs of dmidecode and lspci -vvvv, and /proc/config.gz, in
case this information would be useful.
Please tell me if anything else is needed. I'm willing to invest some
time and have no problem with things like compiling a custom kernel,
using gdb. The only problem here is that I have no idea how I can
trigger this, and can never be sure if the issue went away.
I thank in advance for any help.
Sincerely,
Jeremy.
