The latest snapshot is building right now (now that the >tree builds again...). Look for an announcement on current and scsi in a >little bit. Hmm.. It seems that it has not solved the problems either. :( Since this now seems as it may be scsi related, I'm inluding freebsd-scsi as well. These are the messages that I am getting with the CAM code--they seem very similar. Basically, the system gets so slow that it seems frozen. If you try to switch to the console from X, it will take a long time, but usually it works. :) /kernel.SMP: Timedout SCB handled by another timeout /kernel.SMP: Timedout SCB handled by another timeout ... /kernel.SMP: swap_pager: indefinate wait buffer: device 0x30411, blkno: 8688, size 8192 /kernel.SMP: swap_pager: indefinate wait buffer: device 0x30411, blkno: 8688, size 8192 ... Now that I have blown away my other disk.. I will try moving my swap there, and see if it makes any differenc. Is it likely it is hardware though?
