however the git version of the xserver-xorg-video-intel driver does not
address a couple of crashes with 855 hardware which are caused by the X
driver writing registers in the card.

Shows the diff applied
d be debugged by
the community at large, and perhaps we'd end up with derivative works
(OEM BIOS) of better quality.
Climbing down from the soap box now.

this delay is due to various sleep statements in
the DSDT when not internally handling the backlight etc.. There are also
a lot of OS specific paths in the DSDT for this code, making things even
more fun to trace.

that, and last time I looked, it seemed like it could plausibly be a
Microsoft induced rename / typo, as this method is mentioned for getting
brightness on a Windows Vista compatible box.
Did the bios update also mention any fixes for Vista compatibility?

Is this anything to worry about - should I post a dsdt for the new bios?

o 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 :
C anyway).
I'm presuming ACPI as a good starting point, since that is an area where
AC / Battery may make a difference.
Can anyone suggest a debugging procedure to identify the cause of a
softlock, and where would be appropriate (which category) to file a
kernel bug for this?

This leaves the laptop very toasty if you shut the lid and it does this.
Does yours do this?
Suspend doesn't work out of box, I've not really tried to diagnose.

ed control, had the psmouse
module been removed before reboot.
Unless anyone is keen to know the results, I'm not that motivated to
find out (by upgrading the bios again), as I'm not keen to either wear
out the bios flash chip, or have a random corruption during an update.

CpuPm SSDT? It appeared to
flash correctly when I first installed it. Perhaps even booting windows
(to downgrade to F.06) had some effect on the bios to bring back the
SSDT? Perhaps it is only in the F.06.
Does anyone have any contacts with HP who might shed any light on this?

Clearly to verify this properly, I need to post the DSDT and SSDT in
their entirety, please let me know if I should post them to this list,
or privately email me and I'll send them.
Are these problems "real", or are they simply the symptom of
erested to know if this is an acceptable solution to fix the
problem, or if it simply a workaround to a problem elsewhere.
Perhaps some ACPI guru might have some insight.
