Reproducible: Always Steps to Reproduce: Install 12.1 on a R11CX netbook (presumably all Cedar Trail netbooks). Boot. Kernel oops, see below. (The same with 12.2M2. 11.4 works, but only with fb-graphics.

I am willing to test the patches, if you can provide a repository, from which I can include the kernel at installation time. Since I can't boot, I can't build any kernel myself :-( -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
