Hello,

sorry for posting last mail twice. I thought I entered the wrong mailing 
list address (xfs@xxxxxxxxxxx) first as I read a mailing list mail with 
linux-xfs@xxxxxxxxxxx instead.

I am now running:

root@deepdance:~ -> cat /proc/version
Linux version 2.6.17.1-tp23-sws-2.2.5.3 (root@deepdance) (gcc-Version 
4.0.4 20060507 (prerelease) (Debian 4.0.3-3)) #1 PREEMPT Fri Jun 23 
02:05:35 CEST 2006

I intended to use plain vanilla without sws2 first, but new sws1 seems to 
actually need that user-space stuff for doing suspend. Well at least it 
didnt work here and I read that user space stuff is still experimental, 
thus I decided to use what worked for me.

Things seem to be fine so far, but there is a message once on every boot 
which may indicicate at a harddrive failure. I doubt it - since I did not 
found it in pre 2.6.17 logs -, but it might be the case.

I filed a kernel bug report about this which also contains some diagnostic 
data about the harddisk:
http://bugzilla.kernel.org/show_bug.cgi?id=6737

I am still using disabled write caches for a while. Then I will do a new 
backup and enable them and see what happens. Okay, and now I will do a 
backup, too. Better safe than sorry.

Regards,
