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 :) Rafael J.

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.

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? David Added Linus as it's a regression Added xfs as unmounting an xfs filesystem 'fixes' it. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
