The bug is staill in newer kernels: PATCHLEVEL = 6 SUBLEVEL = 29 EXTRAVERSION = -rc6-mm1 Created attachment 20407 [details]
Dmesg report of the bug
It is dmesg report, when I boot new kernel 2.6.29-rc1-mm1 for example. The X windows will stop without login screen. The processor is hard working.

A lock cannot "take" another lock. And why is f_lock described as "HARDIRQ-READ-irq-unsafe"? It's a spinlock and the "READ" part is not relevant. > > Mar 1 00:07:03 localhost kernel: [ 86.440299] > > Mar 1 00:07:03 localhost kernel: [ 86.440300] and interrupts could > create inverse lock
