Without the NFS4 homedir mount, suspend to ram works perfectly. With
NFS4 homedir, suspend is started, but doesn't complete. Invoking
kernel crashdump, all messages and backtrace looks entirely expected
[1].
Anyone else find the same? Expected to work or not? What information
would help with this?
Thanks,
Daniel

Can you try this with 2.6.30?
