Hi,
I'm seeing this oops on my P4 box running 2.5.66-bk12 + ACPI when shutting it down (copied by hand):
Power down. acpi_power_off called Debug: sleeping function called from illegal context at include/asm/semaphore.h: 119 Call Trace: [<c012088a>] __might_sleep+0x5f/0x75 [<c01ffb10>] acpi_os_wait_semaphore+0xc5/0xea [<c021440c>] acpi_ut_acquire_mutex+0x51/0x73 [<c020ab4f>] acpi_set_register+0x34/0x15d [<c020b1f6>] acpi_enter_sleep_state+0x77/0x1ab [<c0215d7d>] acpi_power_off+0x21/0x23 [<c011a3e5>] machine_power_off+0x10/0x13 [<c0135f7b>] sys_reboot+0x332/0x741 [<c011e010>] schedule+0x210/0x6d7 [<c0130daf>] group_send_sig_info+0x2af/0x6b6 [<c011e50d>] preempt_schedule+0x36/0x50 [<c0131384>] kill_proc_info+0x60/0x62 [<c0134346>] sys_kill+0x4d/0x51 [<c016e76b>] __fput+0xaf/0xfb [<c016cabc>] filp_close+0x160/0x226 [<c01850cb>] sys_ioctl+0x197/0x3e8 [<c010af29>] sysenter_past_esp+0x52/0x71
This is not 100% reproducible. When using ACPI, the machine is *never* able to properly shut it off (only APM is able to turn the machine off).
