        <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!
