After suspend-to-ram the battery is sometimes not readable. The following error

DSDT for the machine
Did this work correctly in earlier kernels? If so which versions?
Please test burst-mode EC patch filed at bug 3851
Suspend did not work on this laptop until very recently (2.6.11) so it is
difficult to tell if this is a regression or not.
I will try the patch and see if the bug seems to go away.
The patch made the error go away but I got a new one instead. The system now
believes that there is no battery connected after a suspend. Reloading 'battery'
has no effect.
Seems to be the same problem as bug #4340 (same hardware, same error messages)
unloading ohci1394 module before S3 suspend could be a temporary workaround
Can you please test 2.6.12-rc5 and provide a status update?
tested whith 2.6.12-rc5 but without patch from bug #3851. the errors are still
present. rmmod 1394ohci prior to suspend solves the problem but then can't have
it working again.
Confirmed. Problem still present on 2.6.12-rc5.
