thanks a lot - that it was ... i did some more testing of it over
the weekend and it looked much more promising than last time i tried
(~ 8 weeks ago) ... got it to hang the machine only once (sorry no
debug output available) - but sofar it worked quite well (even nfs
on top of it seems to run quite good due to my limited testing) -
thanks for all the good work so far ...

i today started to use it here at work too - built the kernel, mkfs'ed
the fs and mounted it - copied the / filesystem over to it - and while
doing this i got:

  kernel: I/O Error Detected.  Shutting down filesystem: ide0(3,5) 
  kernel: Please umount the filesystem, and rectify the problem(s) 
  kernel: PCD: pagebuf_bmap error -5 pb_flags 0x10010002

but the disk did not have any hw error (no ide error to see and the
disk is fresh and fine) - retried it (reboot, mkfs, mount, cp) and
it works now ... will run it in "semi-production" here now - maybe
i can help finding some bugs :-)

also some questions:

* are there any plans to move it towrds a newer test version of the
  2.4.0 kernel ? (because i noticed a lot of the test1 vm problems
  in my tests and for using it on a really used machine it would
  be better to have a kernel without all those problems - which are
  i think partly fixed in the later versions)

* is there any timeframe for a (alpha or beta) working
  xfsdump/xfsrestore ?

also somthing i noticed - looks like one should add the "read-write"
option to the lilo entry if the root is xfs - otherwise it has
problems doe to trying to replay the log on a ro filesystem (paniced
in this case once at home) - this might be (if it is correct)
interesting for other who wanted to try this
