Subject : Regression 2.6.28 and last - boot failed Submitter : jan sonnek <ha2nny@gmail.com> Date : 2009-02-01 19:59 References : http://marc.info/?l=linux-kernel&m=123351836213969&w=4 This entry is being used for tracking a regression from 2.6.27. Please don't close it until the problem is fixed in the mainline.
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
