I get an oops any time when try to poweroff my 2xAthlon MP 2400 box [2.6.3] via SysRq: poweroff. Instead of poweroff i see an oops and box appears to be locked. This is not a significant problem for me, but also not looks like a normal behaviour. Here is a trace: SysRq : Power Off acpi_power_off called bad: scheduling while atomic!
