Summary: lockup in sbshc.c in wait_transaction_complete
Product: ACPI
Version: 2.5
KernelVersion: 2.6.25
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Battery
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Latest working kernel version: 2.6.23
Earliest failing kernel version: 2.6.24
Distribution: Gentoo
Hardware Environment: notebook Acer TravelMate 4502WLMi, Pentium M 1.6GHz, ATI
Mobility Radeon 9700, two monitors (panel+LCD)
Software Environment: N/A
Problem Description:
Reading of /proc/acpi/battery/BAT0/state ends in an endless loop. The first
symptom was that the hald didn't want to finish startup and I figured out that
the problem is in reading the battery status.
I patched (attached) sbs.c and sbshc.c to report method entry/return and also
locking and I found that the execution ends in wait_transaction_complete
(sbshc.c) in an endless wait_event_timeout - really strange.
