After update to 3.5.0 and version above i can turn off laptop with poweroff or power button, but when i try to reboot (via command line) it stalls at very end. And freezes, as well as i can hear FAN is going mad and laptop is getting pretty warm. I think it might be related to https://bugzilla.kernel.org/show_bug.cgi?id=45281 as i think at 3.5.0 somy-modules were updated, though i don't have problems described as there and as well i have those builtin and not built as modules: $grep -i sony /usr/src/linux/.config CONFIG_IR_SONY_DECODER=y CONFIG_HID_SONY=y CONFIG_SONY_LAPTOP=y CONFIG_SONYPI_COMPAT=y Any other information i can provide? P.S. Wasn't sure with category as i'm not 100% sure what is the problem
Can you build a kernel without the sony modules and see if it then behaves, and work back until you've got a minimal kernel or found it. I don't have any idea either so the best beginning is probably to start trying to simplify the causes to suspect.
Sorry for delay. I tried and the result is the same. But as i left it like that for about a half minute, minute it finished restarting. But i had no such performance on 3.4.x it restarted normally, so it's not due software changes, but some changes in kernel. Btw 3.6.0 is the same result.
Bug still present as of 3.11
Since this is a regression, please use git bisect to find the offending commit.
Oh how boring. <mario>Here we go!</mario> john@russia:/usr/local/src/linux$ git bisect start john@russia:/usr/local/src/linux$ git bisect bad v3.5 john@russia:/usr/local/src/linux$ git bisect good v3.4 Bisecting: 6023 revisions left to test after this (roughly 13 steps) [59cd358a7a5b2f6b61faa01dae6cfda3830ac62a] Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Since this bug doesn't exist in 3.14.9-rc6 I wonder if it's worth the effort of doing the git bisect? (I feel like such a dummy for not testing that first).
If there is no such problem on latest upstream kernel, the bisect is not necessary. I'll close the bug.
