Does this also occur with the drm-intel-next branch?  Do you have a
picture of the corruption?

Didn't try this one, went back to 2.6.37-rc4-00292-g3c8cdf9 now.

I thought about following the bisect way, should I go a different
one better?

> Do you have a picture of the corruption?

Not yet, can do one next time. Though I found one that looks
very similar to my corruption:

Though in my case no character was visible anymore.

Cheers,

Nico

Just went that path, compiled 2.6.37-rc4-00292-g3c8cdf9
and suspended which resulted in a completly dead device
(no ping, no ctrlaltdel possible), i.e. different fatal situation.

I'm a bit confused, not sure whether this is related to
the broken display issue or not.

As the tests always cost a quite lengthy fsck run, I'd
love to go a different way from 2.6.37, if anybody has
a better hint.

Cheers,

Nico

commit 8d3bdbd55a7e2a3f2c148a4830aa26dd682b21c4
Author: David S. Miller <davem@davemloft.net>
Date:   Tue Feb 8 15:02:50 2011 -0800

    net: Fix lockdep regression caused by initializing netdev queues too early.
    
    In commit aa9421041128abb4d269ee1dc502ff65fb3b7d69 ("net: init ingress
    queue") we moved the allocation and lock initialization of the queues
    into alloc_netdev_mq() since register_netdevice() is way too late.
    
    The problem is that dev->type is not setup until the setup()
    callback is invoked by alloc_netdev_mq(), and the dev->type is
    what determines the lockdep class to use for the locks in the
    queues.
    
    Fix this by doing the queue allocation after the setup() callback
    runs.
    
    This is safe because the setup() callback is not allowed to make any
    state changes that need to be undone on error (memory allocations,
    etc.).  It may, however, make state changes that are undone by
    free_netdev() (such as netif_napi_add(), which is done by the
    ipoib driver's setup routine).
    
    The previous code also leaked a reference to the &init_net namespace
    object on RX/TX queue allocation failures.
