Subject: Backlight bright-up causes X to restart after HP laptop BIOS
upgrade
I own a HP dv8301nr notebook. It has an AMD64 CPU (running a 32-bit
Debian), ATI chipset and ATI Radeon XPRESS 200M 5955 graphic card. I'm
running an untainted Linux 2.6.19-ck2. X.org is using the open-source
ATI driver.
I upgraded the laptop's BIOS to version F.52 earlier today. Since then
X.org started shutting down every time upon pressing the bright-up key.
Also, the kernel started printing "video device notify" on bright-down
and that same line followed by "set_level status: 0" on bright-up. I
adjust the backlight frequently, so I know for a fact that this was
working yesterday before the BIOS upgrade.
Some relevant parts of my kernel config:
CONFIG_FB=m
# CONFIG_FB_* is not set, not even the Radeon one
CONFIG_BACKLIGHT_LCD_SUPPORT=y
CONFIG_BACKLIGHT_CLASS_DEVICE=m

Although the lcd and backlight modules are not loaded, loading them at
one point didn't seem to help.
I noticed the following change in the ACPI table as reported during the
boot-up sequence. Other than this, I've noticed no other changes:
ACPI: RSDP (v000 PTLTD ) @ 0x000f7c20

Don't hesitate to ask me for anything that could help track this
problem. Please honor the Reply-To header, as I'm not subscribed to this
list.
PS: I upgraded the BIOS, as the new version is supposed to include some
keyboard/mousepad-related fixes for Vista. Since then I haven't
experienced any of the Synaptics mousepad hick-ups that had been driving
me nuts.
Thanks for your time,
