I'm using mdadm exclusively for my imsm raid, and: ~ # find /sys/block -name sync_action ~ # I take it the imsm raid should have that? I used that exact same command (and found nothing) before I posted to the list. >> I've been having issues with suspend which I'm trying to troubleshoot, >> and I know I can stop it if I boot into Windows.

The distro is gentoo (no systemd) - suspend works (as in it goes into suspend properly) but 8 out of 10 times it fails to wake out of suspend by either the keyboard or power button. The only way to "wake" it is to yank the power plug from the PSU for a few seconds and plug it in. As you can imagine, the imsm raid isn't too happy about that... it boots in Verify mode. I've found I can stop the raid verify in Windows, so I thought perhaps mdadm could do the same. I haven't quite figured the suspend issue out yet. It could be hardware (thinking maybe PSU?) but I'm trying to troubleshoot this issue methodologically. It started after an upgrade to a kernel > 3.0.2, I have yet to try a 2.6.x to see if it goes back to normal. When it does resume properly, everything is fine (mdadm doesn't resync.) It's related to the sleep of death (or eternal sleep?) issue.
