Hello Recent -CURRENT seems to have broken aac(4) on a Dell Perc 4/Di. The system is a Dell PowerEdge 2650 with 4 36GB IBM disks in a RAID0+1 configuration. It runs fine on a 5-STABLE kernel, but when booting -CURRENT it prints a lot of errors from the RAID controller and then fails to mount the root file-system. I have attached dmesg from 6-CURRENT and 5-STABLE, but the main interesting parts from -CURRENT are: aac0: <Dell PERC 3/Di> mem 0xf0000000-0xf7ffffff irq 30 at device 8.1 on pci4 aac0: [FAST] aacd0: <RAID 0/1> on aac0 aacd0: 69425MB (142182912 sectors) SMP: AP CPU #3 Launched! SMP: AP CPU #1 Launched!
