Comment 2 for bug 376367

I'm experiencing this as well on a HP Pavilion a730n running a fresh Ubuntu v9.04 install (with all 4 classes of updates enabled). All firmware is the latest available. The messages are not very frequent, apparently occurring only when the system goes out of active cooling mode:

ACPI Error (psargs-0358): [\_TZ_.THRM] Namespace lookup failure, AE_NOT_FOUND
ACPI Error (psparse-0524): Method parse/execution failed [\_GPE._L1C] (Node f6c14450), AE_NOT_FOUND
ACPI Exception (evgpe-0571): AE_NOT_FOUND, while evaluating GPE method [_L1C] [20080926]

Please let me know if there's anything I can do to assist in solving this problem.
