Title:
No wifi after suspend
Status in “linux” package in Ubuntu:

My comment #41 above does not fully apply. It turned out that removing
"iwlwifi" from SUSPEND_MODULES="" in /etc/pm/config.d/config (I had to
add it in 13.10 in order to get it working) fixed the issue for me.
However this seems to imply that unloading the driver will break wifi,
even if network-ma
Indeed I didn't have this issue anymore after making various changes to
the system including updates to mainline kernels. I can not tell if it
is solved in the stock kernels though. I also cannot make tests because
I am not working with this system anymore. You may consider it as 'works
for me'. Th
I do see this kind of problem occasionally when resuming from suspend to
ram and hibernate with the same thinkpad model. I cannot reproduce it
reliably though, but it definitely happens if I suspend often enough.
Kernel 3.8.0-27-generic from kubuntu ppa and also 3.8.0-27-generic-
tuxonice from ppa.
Could you say how it was fixed so I know how to benefit from the fix?

I think I see this with Ubuntu saucy (Kernel 3.11.0-12-generic 64 bit.),
on a Thinkpad T520. I see it even when running on external power and
'link_power_management_policy' set to 'max_performance':

I see this with Ubuntu saucy (Kernel 3.11.0-12-generic 64 bit.), on a
Thinkpad T520 as well. This seems to happen when the system is under
heavy workload and I experience system freezes at the same time (So it
does seem to have a usability impact for me).

Public bug reported:
On Ubuntu 13.10 I encounter kernel reseting SATA link in connection with
temporary system freezes (KDE lags). Such a bug has previously been

I can already say that dmesg prints many of the same error messages with
the mainline kernel 3.12.0-031200-generic . I will report back in case I
don't observe freezes anymore.

I should have mentioned that I see the error message also if the NVidia
Optimus BIOS option is disabled in contrast to what was reported here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/888764 . The error
message is printed about every second even if the system does not
freeze, so I can't
I figured that for me the error messages disappear if you set the SATA
mode to 'Compatibility Mode' instead of 'AHCI' in the BIOS. Ubuntu still
booted after this change. I could not find a relation to the Optimus
