Bug ID: 68421
Summary: Inspiron 3521, kernel hangs after passing
acpi_backlight=vendor
Product: ACPI
Version: 2.5
Kernel Version: 3.12 3.8
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Video
Assignee: acpi_power-vi...@kernel-bugs.osdl.org
Reporter: okit...@ya.ru
Regression: No
The system stops responding on early boot, about as DRM/DRI kicks in, if I pass
it the parameter "acpi_backlight=vendor". SysRQ doesn't work.
No other parameters have been found that cause a similar reaction.
I can't get logs because the system doesn't yet log stuff when it happens.
I am using Debian Testing currently, but the problem has been found in Mageia
with 3.8 as well. It, however, doesn't exist with Ubuntu 12.04 with kernel 3.5
or earlier distributions.
