atl1c: WARNING: at net/sched/sch_generic.c:255 dev_watchdog

[Borislav Petkov]

Hi,

this seems like a pretty old issue judging by a quick net search. It
still triggers on latest -rc4 here, below the whole trace. I'm willing
to test patches :).

Matthew Garrett has a patch to the atl1c driver that changed it's ASPM
behavior that seemed to help.  Dave Miller applied it, but I don't see
it in linux-next for some reason.

May be this is the reason?

I'm also having this issue and can test patches.

Yeah, he reverted them due to build issues. I'm not sure they'll be
coming back though, judging by the thread.

Thanks.
