Is this anything to worry about - should I post a dsdt for the new
bios?
Looking at the ACPI 3.0 spec:
_STM Optional control method that sets the IDE controller’s transfer
timing sttings. IDE-only
(IE. shouldn't be called for an SATA drive). That may mean its for my CD
writer (which shows up as hda). This is in the first SSDT, HPQSAT
which I've attached the dissasembly of.
This means we are unable to set the IDE controller transfer timings
after the
resume. I don't know how serious this is in practice, though.
iasl decompiles and recompiles the dsdt and all ssdt ok (after minor
tweaking due to decompile discrepancies).
The remaining warnings only relate to _BCQ (A Microsoft induced typo for
_BQC?)
And, unreachable code in the _STA method of the ACEL device. (They
have blanked that function off with a Return (0x00). Thats a shame - if
it means what I think (that the acceleration sensor doesn't work).
Many places in the ACEL device code check If (_STA ()) around big blocks
of code, so presumably the AML code for it is not doing a great deal. (I
wounder how Windows uses it - a custom driver perhaps?)
Thanks for the great work on suspend / resume (and of course ACPI
support in general) everyone!

Thanks, Luming Ok, I've tested acpi=off and apm=off with the stock Ubuntu kernel. It didn't softlock with either, but I'll try to use one of the two when booting now to ensure it is consistent. with acpi=off, there was a backtrace printed from an unloved IRQ11, and the sound card wasn't particularly happy. These HP laptops seem very picky - perhaps I should buy an IBM next time for linux! I've filed a bug, #7840, http://bugzilla.kernel.org/show_bug.cgi?id=7840 It is under ACPI/Other. Attached to that bug is dmesg output from the normal AC boot, and battery boots with acpi=off, api=off, also an acpidump output from the normal AC boot. I will check the bios, and vanilla kernel tests when I get chance. Unfortunately, it seems quite hard to get a kernel config which exactly matches a stock Ubuntu one (for keeping as few variables changed as possible). I can recompile a kernel source deb for Ubuntu quite happily, but it produces a huge number of versions, and takes many many hours (brings me back to using linux on a [34]86 :)) Thanks for your input Luming, Len.

My fans seemed to work ok most of the time before, it was the battery status which hung, and the speedstep would never go to full speed. Everything is happy with Ubuntu's kernel 2.6.17-10 and when unloading psmouse as part of the shutdown and reboot scripts. I did dig though psmouse a little, but being a non-expert, couldn't see anything odd. It could be the synaptics driver part I guess, as most people have laptops. It could be that psmouse keeps a serial driver of some sort alive, or a bus active. Perhaps it is still receiving and processing interrupts as the bios tries to reboot?
