Well, I can't. It's been running the test load for almost 24 hours = without any sign of problems. The kernel config is the same as under = 8.1, GENERIC+ipfw (USB not excluded!). Our 8.1 test config includes the = CURRENT debug options, so as far as I can tell we should be testing = under the same conditions. Yet I don't know wether CURRENT includes any = additional debug magic I'm not aware of, which could slow the system = down an prevent the issue from occurring. Another difference to our primary 8.1 test machine is that we didn't use = ZFS on CURRENT. But since we are able to crash 8.1 with UFS, I don't = think this will matter. Still I'm going to try to get together a CURRENT = ZFS setup on the second machine. But, so far, bottom line seems to be: - no problems on 6.x, 7.x and CURRENT - no problems on Linux (that was only a short test though) - crash within a minute on 8.1 (with ehci in the kernel) Unfortunately, I have not been able to get anything useful out the svn = commit logs, which could explain this. Maybe someone else has an idea = what could have changed between 7 and 8 to break it, and again between 8 = and CURRENT to magically fix it again. Markus=
