<pre>Hello Ville,
I tried latest 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
After S3 resume and call trace appear, there are some error dmesg, and cannot
do S3/reboot action again, would you pls help take a look at below dmesg error
and attached s3dmesg.log to see if these error still due to BIOS issue? Thanks
a lot!
