After update from kernel 3.4.6-2.10, boot freezes unless nomodeset kernel parameter is added. Boot ends with kernel bug in timer.c:1085

I am attaching reports from working system - 3.4.6-2.10
Comment 1 Daniel Vetter 2012-10-19 14:33:32 UTC
Can you please attach the kernel bug + backtrace, too? Screenshot (if nothing else) is good enough, if it contains the full oops.

Also, can you please try whether latest 3.6 works?

And: Is this a regression, if so can you please specify the exact upstream commits that last worked and where things started breaking?

Kernel 3.6.3-8 works (but 3.4.11-2.16 is now the current kernel for opensuse 12.2). Did not try any other from 3.4.x than 3.4.6
Comment 5 Daniel Vetter 2012-11-13 12:20:44 UTC
I'm confused here a bit, so please clarify: 3.4.x is broken but more recent kernels like 3.6.x work?

If that's the case, this smells more like a bug you should file with your distro.
Comment 6 Jesse Barnes 2012-12-12 19:35:09 UTC
Yeah sounds like your distro kernel is missing some fixes from upstream.  Maybe they just need to be backported, you can file a bug with them and provide the broken and working versions and they may be able to backport the right bits.
