Sorry Does this issue has the same root cause as S3 issue: https://bugs.freedesktop.org/show_bug.cgi?id=84903 Verified 2014_11_06 drm-intel-nightly branch kernel: [root@x-bsw01 ~]# cat /proc/cmdline BOOT_IMAGE=kernels//nightly_parents/2014_11_06/drm-intel-nightly/0642a51748ff46a 205cf2a3fc45ba18cc92c9bda/bzImage_x86_64 root=/dev/sda4 hostname=x-bsw01 modules _path=kernels//nightly_parents/2014_11_06/drm-intel-nightly/0642a51748ff46a205cf 2a3fc45ba18cc92c9bda/modules_x86_64/lib/modules/3.18.0-rc3_drm-intel-nightly_064 2a5_20141106+ acpi_rsdp=0x7b71d014 kexec_jump_back_entry=0xe84a9118 S4 issue has been fixed, S4 can successfully enter and resume by press power button, and there is no error message in dmesg, so close this bug as fixed.

(In reply to wendy.wang from comment #4) > Created attachment 109992 [details] > s4-fail-dmesg There is no error or backtrace in here. Can you please explain why you reopened this. Also you've confirmed in comment #3 that it works. If it's broken now that's likely a new bug (and a regressions). If that's the case please reset this bug back to verified and open a new bug to track this regression. Closing old verified. |
