           Summary: Failure during resume on NV50: INIT_AUXCH: rd auxch
                    fail -121

Kernel messages from boot thorugh suspend to resume

Upon return from suspend, the display turns white and stays that way. The X
server is unusable. Other VTs as well. The problem is 100% reproducible.

I'm using openSUSE 11.4 RC 1 on an HP 8440p with a NVS 3100m card (GT218M,
thus
NV50-type). I reported first at
https://bugzilla.novell.com/show_bug.cgi?id=669932 and was asked to report
here. 

I'm using packages dating git20110210 from
http://download.opensuse.org/repositories/home:/jobermayr/openSUSE_Factory/x86_64/

Since the problem is reproduced every time, I would be happy to help if I can
provide debugging information. The installation currently is dedicated for this
sole purpose (I need suspend-resume in a would-be production system).

Bugs I found related but IMO still different enough to report this one:

I have a similar problem on the same hardware with Ubuntu 11.04 Alpha 2.
dmesg output contains the same lines:

Probably this bug is similar to bug 27398. Common features:
1. Identical lines in dmesg output (INIT_AUXCH: rd auxch fail -121).
2. Displays are connected via DisplayPort (bug 34429 - eDP, bug 27398 - DP).
3. Displays have not been initialized by BIOS (bug 34429 - after resume, bug
27398 - external display).

No worries.  Thanks for tracking down the root cause of this.  I was aware of
this GPIO function previously, but didn't honestly expect any VBIOS init
table
to default it to off when there was a panel attached :)
