Ok, there's no warning message anymore but maybe a dozen of seconds
delay before the machine is actually powered off.

"...
ACPI: Preparing to enter system sleep state S5
[Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored
<a bunch of seconds of doing nothing>
...
<machine powers off>"

So could it be that some RCU cleanup stuff is going on during that time?

I mean, the issue is not that big of a deal - when the box resumes, the
sound card works just fine so...

Thanks.
