Comment 1 Rolf Eike Beer 2007-09-27 06:38:53 UTC
I see the same problems here with this card (builtin in Toshiba Satellite A110-178). S2disk and wakeup is enough to cure it. First time I noticed it was on August 10th (which was sometime between -rc2 and -rc3).

Comment 2 Francois Romieu 2007-10-04 15:30:29 UTC
The 8101 and the 8168 are different enough for the problem to be different
for each adapter.

Rolf, did 2.6.23-rc1 work correctly ?

Comment 3 Alan 2008-09-23 03:06:17 UTC
No response in over 9 months, closing
Comment 4 Rolf Eike Beer 2008-09-23 04:36:01 UTC
Sorry, this one got lost. No idea, it's an older kernel. Bug is still present in 2.6.26.
Comment 5 Francois Romieu 2008-09-23 14:20:05 UTC
Rolf, is it still present in 2.6.27-rc6 + 

Comment 6 Rolf Eike Beer 2008-09-26 04:20:42 UTC
I have tried with 2.6.27-rc7-git a "svn up ~/repos/KDE" which is a (sparse) SVN checkout of KDE SVN root. This was an absolutely reliable way to cause that timeout. It _was_, it works now.
Comment 7 Rolf Eike Beer 2008-09-29 09:53:54 UTC
Here it is again:
