Hi Venu,
Looks like your graphic device (0x8086, 0x8108) is not supported
by i915 driver which do support S/R.
vgatext doesn't support S/R. You can have a try to manually set
vgatext_force_suspend to 1 in mdb. Anyway, the system may still have
problem in resume even suspend succeed. There's an open CR for this
issue:
6746567 vgatext needs complete Suspend/Resume support
Regards,
Kerry
