I must have missed this part of the manual, sorry for that.

I've attached the output from sysstat vmstat while running vinum (i have 
to admit that i don't get everything of what it's telling me). It's also 
just a snapshot because the interrupt range is dithering from below 3000 
up to 21000).

Trying different disks just gets me to that problem in no time. I got up 
to 15000 interrupts with just one disk without vinum or raidframe. 
(sysstat vmstat also attached).

Whatsmore the problem seems not to be bounded to this promise/wd 
combination. I've got two scsi disks in that machine connected with an 
onboard adaptec scsi controller which have the same problem. Lots of 
interrupts and a bad ping response time.
Anything i could about that? I tried setting "PnP OS" to "No" in the 
BIOS but it didn't help.

Thank you in advance and best Regards,

Jochen Keil

P.S.:
I didn't CC everbody else who answered me because i think they are all 
subscribed to this list. If you'd like me to CC you tell me and i'll do 
so :)
