 I already replied to Sean last friday but the copy has not made its way =
 into the PR system, probably due to the size of the alltrace attachment. =
 So here's a dropbox link:

 Hi again
 
 One of the G8 blades we had booted back into PERF mode yesterday stalled =
 last night. This one was _not_ patched with the ciss changes from head, =
 so it was the plain 9.1 driver running in default PERF mode. This means =
 that as soon as we restore the original default configuration, the =
 stalls come back quite quickly. Of course we still don't know wether it =
 is the patch, SIMPLE mode or the combination of both that seems to help =
 the other systems. Hopefully we'll know that soon.
 
 Anyway, we got an alltrace from the server that stalled. Unfortunately =
 no ciss debug outpout since it was not patched.
 
 
 Markus
