Hiya, We've recently loaded FreeBSD 4.11-STABLE with PAE support onto one of our brand new Dell PowerEdge 2650's. The box has 6GB RAM and with PAE support compiled into our kernel can see it all fine. However when we start doing disk intensive stuff like compiling, our RAID appears to spack out and cause the system to freeze and require a reboot. When logging in via console we see: aac0: COMMAND TIMEOUT AFTER 1540 SECONDS repeated continuously.

Just wondering if anyone else has experienced this or has any insight. The system is running RAID5 with 4 x 73GB SCSI drives: Apr 5 22:30:03 luke1 /kernel: aac0: <Dell PERC 3/Di> mem 0xf0000000-0xf7ffffff irq 16 at device 8.1 on pci4 Apr 5 22:30:03 luke1 /kernel: aac0: i960RX 100MHz, 118MB cache memory, optional battery present Apr 5 22:30:03 luke1 /kernel: aac0: Kernel 2.8-0, Build 6092, S/N 64a1d3 Apr 5 22:30:03 luke1 /kernel: aac0: Supported Options=275c<WCACHE,DATA64,HOSTTIME,WINDOW4GB,SOFTERR,NORECOND,SGMAP64> Thanks :) -- jeremy bogan [ jeremy@segpub.com.au ] segment publishing - design.develop.host
