With all the great work happening around the different flavors of zzz I
thought I'd try to test some of this on my desktop. This machine wakes up
reliably from suspend in Linux. Some days it even wakes up in OpenBSD,
but mostly I see the machine wake up and then panic with this message:
kernel: protection fault trap, code=0
Stopped at sd_buf_done+0x18: movq 0x38(%rax),
ddb{0}>
Rarely it crashes differently:
attempt to execute user address 0x0 in supervisor mode

end trace frame: 0x0, count: 8
The system seem to be getting restored pretty close full operations: USB
devices get reattached and the input is processed by shell. And yet,
something is not quite there.
The traces above are OCR'd, the original images are at
https://photos.app.goo.gl/C1gpB9QifPZNECx56
DDB doesn't like my USB keyboard, so further examination is not easy.
I uploaded the contents of my /var/db/acpi to cvs:~gnezdo/asus-acpi.tgz
The kernel I'm running includes the intelpmc work, but the crashes have
been there all along, so I don't expect this to be related.
