I'm sure this isn't the address to send this to, but I don't know where to send this. I just upgraded from 2.4.0-test12 to 2.4.0, and I got a kernel panac after about 6 hours. Then updated to 2.4.0-ac4 and got a massive amount of scsi errors. The server was again up for about 6 hours. This was in the syslog: ----------------------------------------------------------------- Jan 8 16:51:34 kenny kernel: (scsi0:-1:-1:-1) Referenced SCB 12 not valid during SELTO.

I will atach my current dmesg. Thanks for any help Dave Joyce ProbeTalk.com server admin
