Hello!
 
I have some troubles with southbridge i82801gx.
 
I can boot Windows on my board, but S3 from OS doesn't work properly if i resume with USB keyboard.
 
In this case, i have Wake signal and coreboot starts to boot, but it stucks with endless messages about SMI# "GPE0_STS: USB1":
 
...
 
SMI# #0
GPE0_STS: USB1
 
SMI# #0
GPE0_STS: USB1
 
SMI# #0
GPE0_STS: USB1
 
....
 
These messages come from file "\southbridge\intel\i82801gx\smihandler.c", function "dump_gpe0_status".
 
According to i82801gx datasheet:
___
 
USB1_STS — R/WC. Software clears this bit by writing a 1 to it.

0 = USB UHCI controller 1 does Not need to cause a wake.

1 = Set by hardware when USB UHCI controller 1 needs to cause a wake. Wake event

will be generated if the corresponding USB1_EN bit is set.

___

Clearing of GPE0_STS bits properly done in function reset_gpe0_status
 
 
/**
 * @brief read and clear GPE0_STS
 * @return GPE0_STS register
 */
static u32 reset_gpe0_status(void)
{
 u32 reg32;
 
 reg32 = inl(pmbase + GPE0_STS);
 /* set status bits are cleared by writing 1 to them */
 outl(reg32, pmbase + GPE0_STS);
 
 return reg32;
}
 
So... i can't really understand, why does this SMI# appear again and again?
 
Thanks,
Aladyshev Konstantin.
