SCSI troubles

[Tomas Randa]

Hi,

I Am running 5.4-STABLE FreeBSD 5.4-STABLE #0: Sun May  8 18:23:40 CEST 
2005 with Adaptec 29320 or 2930U2 controller and with heavy load on SCSI 
I have the following problems ending with system freeze. Have anybody 
some opinion where could be problem?

Thanks a lot Tomas Randa
