Subject: pm-susend on 2.6.30-rc5
When trying suspend on 2.6.30-rc5 I get the following WARN and also
cannot use my write to my file system. I cannot even reboot:
mcgrof@...o ~ $ sudo reboot
sudo: unable to execute /sbin/reboot: Success
mcgrof@...o ~ $ echo $?
127
Granted, I've never tried to suspend on this box, its a development
desktop, but still think you'd like to know about it. The actual WARN
in question is:
/* Warning on suspend means the RTC alarm period needs to be
* larger -- the system was sooo slooowwww to suspend that the
* alarm (should have) fired before the system went to sleep!
*
* Warning on either suspend or resume also means the system
* has some performance issues. The stack dump of a WARN_ON
* is more likely to get the right attention than a printk...
*/
WARN(msec > (TEST_SUSPEND_SECONDS * 1000), "Component: %s\n", label);
But what is surprising is this is a decent desktop: AMD Phenom(tm)
9750 Quad-Core Processor with 8 GB RAM. not sure what to make out of
this WARN then or what to do.
The hard drive (sdb) / ext3 issues seem separate. Below I paste the
WARN and some sda/ext3 errors.

I've booted with nmi_watchdog=1 (which doesn't work see bug #12774)
and apic=debug.

In suspend.log you'll find a cfg80211 related lockdep warning -- I am
testing WoW code but I do not believe the lockdep issue is related to
that code so that should be reproducible without ithe WoW stuff I
have. Anyway if anyone has an idea how to fix this issue that the WARN
complains about please let me know. The sdb/ext3 issues are a little
more concerning. Not like I care but others using similar systems and
for whatever reason they suspend (I guess to save power at home on a
power hog machine) may.
