This started as a non-regression bug-report about wakeonlan During tests I found a real regression and this email is only about 2.6.22-rc3 without Rafael's patches - which I'll happily come back to later :)

Given that I expected it to fail I unmounted my 1Tb array data before suspending. It succeeded... so I started digging...
So I tried again. 2.6.22-rc3 (vanilla) suspended OK this time but on resume hung at: Stopping tasks done Shrinking memory done (0 pages freed) Freed 0 kb in 0.0 secs (0.0MB/s) Suspending console(s)
Then 2.6.22-rc3 again but CONFIG_DISABLE_CONSOLE_SUSPEND=y It suspended again. Froze on restore. Screen photo here: http://www.dgreaves.com/pub/2.6.21-rc3-resume-failure.jpg
Then 2.6.22-rc3 again but CONFIG_DISABLE_CONSOLE_SUSPEND=y This time, before suspending I unmounted my xfs/lvm/raid6 filesystem. Just a umount, I left the devices/array up. It suspended again. This time it resumed without fault.
The machine has another xfs filesystem : /dev/hdb2 on /scratch type xfs (rw)
I've started bisecting... any other info needed?

Added Linus as it's a regression Added xfs as unmounting an xfs filesystem 'fixes' it.
