I've just uploaded 0.9.8 to http://www.meadowcourt.org/downloads

As a reminder, the wiki page is

This release fixes a bug which could be hit under high disk load (high
number of outstanding requests with fragmented sg lists) and would
reduce performance dramatically - my iometer testing went from 23MB/s to

Also, xenvbd will now dump some stats to the kernel debug logs (use
debugview from sysinternals to view these) every 60 seconds. I'm not

Well after upgrading 0.9.6 (actually, first uninstalled those with the pre-0.9.0 instructies because of bsod when doing normal upgrade) I get instant lockups when doing anything I/O intensive! The domU will use 100% CPU and just hangs forever as it seems (destroyed it after 5 min). The previous 0.9.6 seemed to be pretty stable, no lockups or whatsoever (and I'd already liked it's HD performance!) So not sure what's going wrong here, but in the meantime I get back to 0.9.6 (or I'll might also test 0.9.7 to clear things up).
