Hi, I double checked the option is enabled. $ grep CONFIG_X86_RESERVE_LOW_64K /usr/src/linux-2.6.33-ck/.config CONFIG_X86_RESERVE_LOW_64K=y I also saw the Suspend-Resume log[1], this does not happen always but 4/5 times. This is a assembled box with award bios and my motherboard is Gigabyte G31M-2SL. I am unsure on how to followup on this error. any help? [1] http://is.gd/cvo43 Regards, Gaurish Sharma
