S3 resume on Fujitsu-Siemens Amilo A7620 (CONTINUES)

[Alberto Piai <albeclemit-whZMOeQn8C0@public.gmane.org>]

Please refer to threads "ACPI S3 resume only reboots" and "[PATCH] GDT table patch for resume only reboots problem" for history on this thread. I moved to a new one because was becoming hard to follow.

Properly using beeping code by Pavel I was able to follow the code after
	wakeup_pmode_return:
		movw	$__KERNEL_DS, %ax
		movw	%ax, %ss
and verified that it doesn't hang at that point.

Wakeup works until:
[...]
# and restore the stack ... but you need gdt for this to work
	movl	saved_context_esp, %esp

	movl	%cs:saved_magic, %eax
	cmpl	$0x12345678, %eax
	jne	bogus_magic

	# jump to place where we left off
	movl	saved_eip,%eax
	jmp	*%eax		###BEFORE THE JMP IT'S STILL ALIVE!
[...]

If i let it enter the jmp, it hangs. How can i follow that jump? Does that mean that we're going out of wakeup.S, finally? That would be a progress.

Current situation is:
with wakeup_addr.patch, wakeup_gdt.patch and 
	movl  %cr0, %eax
	andl  $0xfffffff0, %eax # TS/EM/MP bit off	
	movl  %eax, %cr0
placed at the beginning of wakeup code as suggest by Hiroshi 2 Itoh
the laptop still doesn't survive pushl $0, that causes reboot.
Commenting out pushl $0 and popfl it goes on until the point reported above.

Thanks,
Alberto
