>Description:
When i run the command mkdir /usr/ports on my server (or any other commands using the filesystem), these messages repeats itself for a long time, before it crashes:

ips: cmd polling not implemented for copperhead devices
ips: cmd polling not implemented for copperhead devices
ips: cmd polling not implemented for copperhead devices

ips: cmd polling not implemented for copperhead devices
sem bit still set, can't send a command
ips: cmd polling not implemented for copperhead devices
ips: cmd polling not implemented for copperhead devices
...

I'm not sure what to do with this, but could this have anything to do with gvinum, because the system worked fine before i set up gvinum.

>How-To-Repeat:
Use a IBM ServeRAID II controller, setup gvinum, do IO operations to disks.
