Summary: OQO 01+ doesn't power off since 2.6.24
Product: ACPI
Version: 2.5
Kernel Version: 2.6.28.2+
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Off
AssignedTo: acpi_power-...@kernel-bugs.osdl.org
ReportedBy: j...@lentin.co.uk
Regression: Yes
Since 2.6.24, my OQO 01+ will not enter S5. There are no abnormal messages,
however the device sits in the halted state. Weirdly, S3 & S4 are fine. Using
git bisect, the commit that caused S5 to stop working is:-
http://git.kernel.org/?p=linux/kernel/git/aegl/linux-2.6.git;a=commit;h=c95d47a868f35cd47643d116a3c680cdaa954df8
ACPI: Separate invocations of _GTS and _BFS from _PTS and _WAK
In particular, the call to GTS in acpi_enter_sleep_state is upsetting
something.
I have tried the following:-
* Moving the GTS method call to the beginning of acpi_enter_sleep_state(), this
has no effect.
* Removing the GTS method call entirely results in working S5---obviously I
won't be submitting this patch but keeps me happy for now.
Any suggestions as to what to try next for a better fix?
Basic debug info can be found here:-

Thanks for any help
