Hi,

I have just installed 4.3S from around 6am GMT, over an older 4.2S. I have:

ahc0: <Adaptec aic7890/91 Ultra2 SCSI adapter> port 0xd800-0xd8ff mem
0xf9eff000-0xf9efffff irq 10 at device 11.0 on pci2
aic7890/91: Wide Channel A, SCSI Id=7, 32/255 SCBs

Which during boot gives me:

But from an older build:

Mar 29 15:13:03 doubledragon /kernel: da1 at ahc0 bus 0 target 4 lun 0

da0 has dropped to 10.000MB/s for some reason. No physical changes have been
made, it's a remote machine.

Any ideas anyone?
