My speculated cause might be wrong, as it seems to not be resuming consistently again. This happens most often when I switch power states while the machine is suspend to RAM (e.g., detach the power cord and resume). If it doesn't resume properly, I can get it to resume by plugging it in and unplugging it until it resumes (usually after doing this 2 or 3 times). If I just leave the machine when it is in this state, it will not resume by itself.
Occasionally after forcing a resume by the power cycling method, I get messages like the following in an open terminal: Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] Oops: 0000 [#1] Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] SMP Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] CPU: 0 Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] EIP is at 0x0 Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] eax: dffdeb30 ebx: c2138b64 ecx: 00000000 edx: 00000081 Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] esi: c8849d1c edi: dff94c40 ebp: f2e95d40 esp: dff07f40 Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] ds: 007b es: 007b ss: 0068 Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] Process kacpi_notify (pid: 17, threadinfo=dff06000 task=dff93030) Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] Stack: c0202612 f2e95d40 f2e95d4c c01fcc8d dff94c40 f2e95d48 c0132702 00000000 Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] dff06000 00000000 dff94c4c dff94c60 00000292 c01fcc6f dff06000 dff94c4c Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] dff94c54 dff94c40 c01332e7 00000001 00000000 00000000 00010000 00000000 Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] Call Trace: Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] <c0202612> acpi_ev_notify_dispatch+0x4c/0x55 <c01fcc8d> acpi_os_execute_deferred+0x1e/0x27 Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] <c0132702> run_workqueue+0x72/0xf0 <c01fcc6f> acpi_os_execute_deferred+0x0/0x27 Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] <c01332e7> worker_thread+0x117/0x140 <c011bde0> default_wake_function+0x0/0x10 Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] <c01331d0> worker_thread+0x0/0x140 <c0135f8b> kthread+0xab/0xe0 Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] <c0135ee0> kthread+0x0/0xe0 <c0101005> kernel_thread_helper+0x5/0x10 Message from [EMAIL PROTECTED] at Sun Feb 11 10:36:53 2007 ... thinkpad kernel: [17257086.340000] Code: Bad EIP value.
