Subject: 2.6.14-rc5 apm suspend failure--ALSA patch?
Date: Sun, 23 Oct 2005 14:42:02 -0400 [thread overview]
Message-ID: <20051023184202.GB10037@fieldses.org> (raw)
When I upgraded my laptop (Thinkpad X31) from 2.6.14-rc1 to 2.6.14-rc5 I
found apm suspend had stopped working. With git bisect I found the
commit 16dab54b8cbac39bd3f639db5d7d0fd8300a6cb0, "[ALSA] Add
snd_card_set_generic_dev() call", and verified that suspend worked again
in 2.6.14-rc5 with that patch reverted.
The symptoms are that when I suspend to RAM, the screen blanks but
nothing further happens. At that point I can ssh into the laptop and
find the appended oops. Any idea what's going on?--b.
