[1.] One line summary of the problem:
Attempt to activate swsusp yields: "sleeping function called from illegal context"
[2.] Full description of the problem/report:
Echoing '4' to /proc/acpi/sleep does not sleep the machine but causes a debug message to appear in /var/log/messages, see section 5. below
[3.] Keywords (i.e., modules, networking, kernel):
ACPI, sound, swsusp
[4.] Kernel version (from /proc/version): Linux version 2.5.40 (root@localhost.localdomain) (gcc version 2.95.3 20010315 (release)) #2 Wed Oct 2 13:52:25 PDT 2002
[5.] Output of Oops.. message (if applicable) with symbolic information resolved (see Documentation/oops-tracing.txt)
No oops, but here's the debug info: Oct 3 17:46:21 dhcp-362-41 kernel: Debug: sleeping function called from illegal context at /usr/src/linux-2.5.40/include/asm/semaphore.h:119 Oct 3 17:46:21 dhcp-362-41 kernel: c9b27c70 c01122e4 c0323180 c03a26a0 00000077 c1361600 c0 2afb63 c03a26a0 Oct 3 17:46:21 dhcp-362-41 kernel: 00000077 c9b26000 c12b55fc 00001000 00000000 0000 0004 00000000 c02b17e7 Oct 3 17:46:21 dhcp-362-41 kernel: c12b55fc c9b26000 c12b55fc c02b1bf8 c12b55fc 0000 4140 00000000 c9b26000 Oct 3 17:46:21 dhcp-362-41 kernel: Call Trace: Oct 3 17:46:21 dhcp-362-41 kernel: [<c01122e4>]__might_sleep+0x54/0x58 Oct 3 17:46:21 dhcp-362-41 kernel: [<c02afb63>]snd_pcm_prepare+0x21/0x1dd Oct 3 17:46:21 dhcp-362-41 kernel: [<c02b17e7>]snd_pcm_common_ioctl1+0x19a/0x238 Oct 3 17:46:21 dhcp-362-41 kernel: [<c02b1bf8>]snd_pcm_playback_ioctl1+0x373/0x381 Oct 3 17:46:21 dhcp-362-41 kernel: [<c02a7886>]snd_pcm_oss_get_space+0x47/0x120 Oct 3 17:46:21 dhcp-362-41 kernel: [<c02b1f69>]snd_pcm_kernel_playback_ioctl+0x27/0x30 Oct 3 17:46:21 dhcp-362-41 kernel: [<c02b1fc5>]snd_pcm_kernel_ioctl+0x23/0x3c Oct 3 17:46:21 dhcp-362-41 kernel: [<c02a67e6>]snd_pcm_oss_prepare+0x15/0x31 Oct 3 17:46:21 dhcp-362-41 kernel: [<c02a6834>]snd_pcm_oss_make_ready+0x32/0x3e Oct 3 17:46:21 dhcp-362-41 kernel: [<c02a6b8f>]snd_pcm_oss_write1+0x2f/0x12e Oct 3 17:46:21 dhcp-362-41 kernel: [<c02a8809>]snd_pcm_oss_write+0x32/0x67 Oct 3 17:46:21 dhcp-362-41 kernel: [<c0138a08>]vfs_write+0xaf/0x12a Oct 3 17:46:21 dhcp-362-41 kernel: [<c0138ae8>]sys_write+0x2a/0x3b Oct 3 17:46:21 dhcp-362-41 kernel: [<c0106eab>]syscall_call+0x7/0xb Oct 3 17:46:21 dhcp-362-41 kernel:
