Subject: [BUG][2.6.38] IRQ Lock Inversion / i915 fails

Hi everybody!

Well, I updated my test partition to opensuse 11.4.

The opensuse standard kernel is unusable for me, booting hangs
most of the time, the same is true for shutdown. If booting succeeds the
system will fail after a short time of usage.

So I installed kernel 2.6.38.  That helped a lot ... for a few minutes.

A possible irq lock inversion is detected during boot, after a short time
X fails, restarting the X server does not work, a reboot is necessary.

Attached find lspci output, kernel config and kernel debug messages.

cu,
 Knut
