https://bugzilla.kernel.org/show_bug.cgi?id=77201 --- Comment #82 from Mauro <registosites@xxxxxxxxxxx> --- I have managed to narrow this down to a function, specifically: cpufreq_notify_transition(policy, &freqs, CPUFREQ_POSTCHANGE); Now this is from cpufreq and not powenow-k8, I haven't tried doing anything inside cpufreq.c because I don't know if it would work just (moving the if-return) or if that would be a mistake. I'm attaching logs of stop_transition before and after cpufreq_notify_transition() as they seem to be slightly different. When the machine hangs I only see my message about changing freq to 1.8GHz, there is no more output to screen before the machine hangs. -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
