Subject: Warnings about tasks on CPU 1 during STR
Date: Mon, 25 Jan 2010 05:42:07 +0100 [thread overview]
Message-ID: <201001250542.08642.elendil@planet.nl> (raw)
With 2.6.33-rc5 during suspend to RAM I'm getting a bunch of warnings
I've not seen with earlier kernel versions:
PM: late suspend of devices complete after 28.784 msecs
ACPI: Preparing to enter system sleep state S3
Disabling non-boot CPUs ...
CPU 1 is now offline
SMP alternatives: switching to UP code
Task events/1 (pid = 10) is on cpu 1 (state = 1, flags = 84208040)
Task khelper (pid = 11) is on cpu 1 (state = 1, flags = 80208040)
Task sync_supers (pid = 77) is on cpu 1 (state = 1, flags = 80208040)
Task bdi-default (pid = 79) is on cpu 1 (state = 2, flags = 80a15040)
Task kblockd/1 (pid = 81) is on cpu 1 (state = 1, flags = 84208040)
[...]
Task pm-suspend (pid = 29782) is on cpu 1 (state = 2, flags = 414000)
Extended CMOS year: 2000
Back to C!
All the "Task X is on cpu 1" messages (76 in total) are new. Bug or
intentional? As it is a warning, I suspect a bug.
Cheers,
FJP
