RHBA-2010:0256 - Bug Fix Advisory

Topic

Updated hal packages that fix various bugs are now available.

Description

HAL is a daemon for collecting and maintaining information relating to
hardware from several system sources.

The updated packages fix the following bugs:

• a sanity check in the HAL init script was incorrectly exiting with error

code 0 when the script could not locate /usr/sbin/hald. The updated
packages now contain a stronger sanity check, which returns the correct
error code for a given condition. (BZ#238113)

• a missing FDI quirk parameter for IBM X31 laptops prevented the laptop

monitor from switching off during suspension. The updated packages add an
extra "merge" element to the X40/X30 FDI definition, which correctly sets
the dpms_suspend power management attribute. (BZ#395991)

• a suspend hotkey combination (Fn+F1) used on Dell Latitude hardware was

not mapped correctly. While the keycode sequence could be set manually,
owners of Dell Latitude equipment experienced unnecessary inconvenience
when attempting to suspend using the hotkey combination. The updated
packages add the correct mapping rules, which enable the Fn+F1 key
combination. (BZ#450326)

• when HAL checked for ttyS devices, it would abend if /sys/class/tty/ttyS*

existed but /dev/ttyS* was removed or modified. Customers using two or more
PCI serial port boards (with port extension) often implemented scripts to
rename the port labels on the hardware to match the /dev/ttyS* node. HAL
checks did not correctly cater for this scenario. The updated packages
check whether serial device nodes have been manually removed. (BZ#486427)

• a missing HAL video quirk setting prevented IBM 4838-310 POS units from

resuming correctly from S3 suspend state. The updated packages include a
vbe_post quirk that corrects the suspend issue. (BZ#501726)

• an incorrect parameter in /etc/udev/rules.d/90-dm.rules prevented

LUKS-formatted (encrypted) USB disks from automounting using GNOME.
Customers had to mount the drive manually, or comment out the ignore_device
line in 90-dm.rules to effect the change. The updated packages
fully implement this workaround solution. (BZ#519645)

• a missing HAL suspend quirk parameter prevented owners of Lenovo ThinkPad

T400 laptops (product key 2768A96) suspending and resuming a session from a
previously suspended system. The issue presented on laptops with ATI
Mobility Radeon HD 3400 Series chipsets (1002:95c4), or Intel Mobile 4
Series chipsets (8086:2a42). The updated packages fix the suspend issue by
correctly specifying the --quirk-vbe-post option for T400 machines.
(BZ#571925)

All hal users are advised to upgrade to these updated packages, which
resolve these issues.
