[ltp] T43p problem with ACPI and battery status

Hi,

I'm running a T43p with kernel 2.6.14-1.1637_FC4 (including the SATA
patches).  Every now and then the battery applet will stop showing
battery status.  BAT0/state seems fine, however BAT0/info gives:

  $ cat /proc/acpi/battery/BAT0/info
  present:                 yes
  ERROR: Unable to read battery information

syslog contains lots of these messages:

  ACPI-0213: *** Error: Method reached maximum reentrancy limit (255)
  ACPI-0508: *** Error: Method execution failed [\_SB_.PCI0.LPC_.EC__.BAT0._BIF] (Node c18e0bc0), AE_AML_METHOD_LIMIT

I tried booting with acpi_serialize and so far it seems to do the trick.
Anyone else seeing this?

Thanks,
