ATA failure at resume on ThinkPad X40

[Takashi Inoue]

Hi friends,

I am using 5.3R on ThinkPad X40.
When it resume from ACPI S3 sleep, an ATA failure occur as:
----------------------------------------
ioapic_suspend: not implemented!
ad0: FAILURE - ATA_IDENTIFY timed out
ad0: WARNING - removed from configuration
----------------------------------------
Then, I cannot do even shutdown.
Therefore I don't use suspend/resume on my ThinkPad now.
It is pity. Does anyone know a reason and solution of it?
Or, does anyone here use ACPI S3 successfully on X40?
Disabling apic helps. But I prefer to use apic because of better response.
Any infomation and comment is welcome. Thanks.

Cheers,
Takashi
