It happened again. Above is the log extract from another oops --- in the same appication, gkrellm. Backtrace is more or less identical. It also happened shortly after a resume from hibernate, where I noticed that the ACPI state had become confused anyway (kernel thought power was plugged in, when running on battery).
Happened yet again in 2.6.17-1.2174_FC5 with gkrellm. Log excerpt follows.

Created attachment 142109 [details] Log excerpt with fourth oops. ACPI subsystem oops, this time in kernel-2.6.18-1.2849.fc6 during a hald syscall.
Seems to have been mitigated by using ec_intr=0 and acpi_serialize options.
