	Julian,

	I have made some tests. First server (XVR500, 2*US-III/750) remains in 
same configuration and is stable.

	I don't understand why I cannot put a XVR500 in second one. System 
starts but screen was unusable (display takes a bad resolution and was 
scrambled). In a first time, I thought my second XVR500 was dying. But I 
have a third Blade 2000 in the same place and this XVR500 runs fine in 
third Blade 2000... Why ? I don't know. And all PCI slot run fine in 
server where XVR500 doesn't work...

	Thus, I have swapped both servers. I have tested third one with Creator 
3D (new creator3D, new memory, one new CPU, one retired from second 
server...) and it hangs like second one. The last night, I have 
installed XVR500 and removed Creator 3D). Now, server is stable enough 
to build NetBSD from sources and pkgsrc :

load averages:  7.36,  7.20,  7.02;   up 0+11:33:42        11:54:04
145 processes: 5 runnable, 137 sleeping, 1 zombie, 2 on CPU
CPU states: 79.4% user, 0.0% nice, 20.6% system, 0.0% int, 0.0% idle
Memory: 1078M Act, 543M In, 9192K Wired, 71M Exec, 1264M File, 42M Free
Swap: 8050M Total, 143M Used, 7907M Free

	I suspect a bug somewhere in UPA support as you said.

	Best regards,

	JKB
