Earliest failing kernel version: 2.6.26-rc7
Hardware Environment: laptop Dell XPS M1210, x86_64
I have problem with video restore therefore I have tried to boot with 'acpi_sleep=s3_bios'. The system hangs on wake up on line 'asm volatile("lcallw $0xc000,$3");' at arch/x86/kernel/acpi/realmode/wakemain.c
I have applied patch http://bugzilla.kernel.org/attachment.cgi?id=16604. See bug #10927 for more details. Probably this bug can be related with #10927.
Steps to reproduce:
1. Boot with 'acpi_sleep=s3_bios'.
2. Suspend to RAM.
3. Hangs on wake up.
