--- Comment #22 from Manuel Ullmann <[email protected]> 2010-02-09 20:58:17 --- Created an attachment (id=24980) --> (http://bugzilla.kernel.org/attachment.cgi?id=24980) syslog-ng output of an isuue caused by BIOS. @Alex Deucher: You mentioned earlier some 'scratch reg bits'. What are they doing? How could they fix issues specific to certain systems like the Compaq 6735b series? Your patch at http://people.freedesktop.org/~agd5f/0001-drm-radeon-kms-add-additional-safe-regs-for-r4xx-rs.patch seems to be related to those bits, but it is specific to some graphic chips. I have experienced, that waking up from S3 or S4 can indeed change the brightness with kms. As mentioned in Comment 12, the brightness uninitialized until it is changed. /sys/class/backlight/acpi_video?/backlight has the value 0, although the backlight has full brightness, which should be 24. When hibernate-script reinitializes the backlight, it is switched to its lowest brightness. So I can choose now between the highest and lowest brightness. But nevertheless the main issue, that the system freezes after certain amount of inactivity, remains. I understand, that the firmware is not likely to be updated and that instead the kernel framework around it maybe has to be fixed. Of course this could be also BIOS-related, as I had already an issue, which was caused by an error in BIOS with this notebook (see attachement). But as this Bug is not OS-independent, I doubt that it would be fixed ever. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
