The first mode (selected with mode_option or during boot) is ok but every mode switch with fbset locks up computer. If the commit is reverted mode switching works correctly. I do not understand why. I would be grateful if someone else can confirm the problem as well. The commit's details are: commit 66c1ca019078220dc1bf968f2bb18421100ef147 Author: Andrea Righi Date: Tue Mar 31 15:25:18 2009 -0700 fbmem: fix fb_info->lock and mm->mmap_sem circular locking dependency Regards, Krzysztof ---------------------------------------------------------------------- Kto lepiej radzi sobie w kuchni?
