The -current branch has better granularity so it would be best to do it from there. I cannot reproduce this behavior on my hardware, so I've resorted to an inspection of all changes since April 1. Narrowing this down to one revision would greatly help me to find the problem. >For what it is worth I checked the difference between boot up with the >old good kernel vs the new hanging kernel and found two differences. >The new kernel has this extra line: >ahc0: BurstLen = s, Latency Timer = 64PCLKS ^^^<= It didn't give you a number here? >The new kernel was also different on this line: >ahc0: aic7880 Wide Channel , SCSI Id=7, 16 SCBs >the old kernel said: >ach0: aic7880 Wide Channel, SCSI Id=7, 256 SCBs This is to be expected.
