Bug#697635: [3.6.9 - 3.7.1 regression] Dell D630: System doesn't reboot nor power off
fixed 697635 3.9.8-1 thanks Dear Maintainers, Problem fixed in 3.9.8-1, certainly because of commit 67842e50729b9f9c9ebd1449735f2f3d129e2325 (in 3.9.7) regards, Nicolas
Bug#697635: [3.6.9 - 3.7.1 regression] Dell D630: System doesn't reboot nor power off
Dear maintainers, I have finally finished my second bisect with f96972f reverted, unfortunately the kernel doesn't boot for a big part of the bisection and I cannot point a single bad commit. $ git bisect skip There are only 'skip'ped commits left to test. The first bad commit could be any of: 3e339b5dae24a7065e196eb8d0145ab2f8cc2d2d bcd951cf10f24e341defcd002c15a1f4eea13ddb 3180d89b47701072cf129f800a735baf3acdbb8a 62ab7072476ae1600e877cc62b43758e485f4f1e 81942621bd6b70b1a1ac4692b3f8f3be65a91b44 f97f8f06a49febbc3cb3635172efbe64ddc79700 2a1d446019f9a5983ec5a335b95e8593fdb6fa2e c0e12e51b0522f7f5f09ea90273dbb724afb054d 5d01bbd111d6ff9ea9d9847774f66dff39633776 bff4a394795add6b919debc009f72b7607f5d4bf 5217192b85480353aeeb395574e60d0db04f3676 We cannot bisect more! git bisect log is attached. I'll try to find what's preventing kernel to boot. Perhaps related to bug 686040 according to the boot log, I'll see if applying commit 092369e could help. I've now upgraded to 3.8 then 3.9 and reboot and poweroff are mostly functionals (fails very rarely contrary to 3.7) but I cannot make my laptop to hibernate anymore now (suspend ok, but resume to a black screen and switching VT doesn't work), I'll try to check if s related. regards, Nicolas git_bisect.log Description: Binary data

tags 697635 + patch
thanks
Ok reverting commit f96972f on 3.7.1-1~experimental.2 fixes my problem.
But, as I said, this particular commit was backported to 3.6.2 and
didn't trigger the freeze there. I'll try to dig a little more to see
where real problem hides.

Bug#697635: [3.6.9 - 3.7.1 regression] Dell D630: System doesn't reboot nor power off
I have bisected the problem to commit : f96972f2dc6365421cf2366ebd61ee4cf060c8d5 is the first bad commit commit f96972f2dc6365421cf2366ebd61ee4cf060c8d5 Author: Shawn Guo shawn@linaro.org Date: Thu Oct 4 17:12:23 2012 -0700 kernel/sys.c: call disable_nonboot_cpus() in kernel_restart() As kernel_power_off() calls disable_nonboot_cpus(), we may also want to have kernel_restart() call disable_nonboot_cpus(). Doing so can help machines that require boot cpu be the last alive cpu during reboot to survive with kernel restart. This fixes one reboot issue seen on imx6q (Cortex-A9 Quad). The machine requires that the restart routine be run on the primary cpu rather than secondary ones. Otherwise, the secondary core running the restart routine will fail to come to online after reboot.

Strangely this commit has been backported to 3.6.2 and I can also find it in linux_3.6.9.orig.tar.xz so, but I don't have any problem with the 3.6 kernel so it seems to trigger something else in the 3.7 era. Or bisecting between 3.6 and 3.7 on linux-stable isn't possible ? I've atached the log just in case I made a mistake. I'll try to revert this particular patch on 3.7.1-1~experimental.2 and see what happens.
