Happened once to me. I actually thought my battery was dying, so I went into the BIOS and did a battery cycle (full discharge). Hasn't come back since, but I'd guess that was a co-incidence. Probably needed it anyway.
Feb 21 18:32:10 kosh kernel: ACPI-0279: *** Error: Looking up [NACH] in namespace, AE_ALREADY_EXISTS Feb 21 18:32:10 kosh kernel: ACPI-1120: *** Error: Method execution failed [\_SB_.BAT0._BST] (Node c7f88ba0), AE_ALREADY_EXISTS
Was running 2.6.3 (vanilla) at the time. Uptime at this point (first mention in logs) was ~1 day, 1 hour & 15 mins. Probably haven't had >24 hrs uptime since then. Will have this weekend (for testing).
Laptop is an Asus L7300/L7200 (PIII-600 on 440MX chipset) with the latest BIOS. Currently running 2.6.4-rc2 vanilla.
