This is very interesting. It seems to there are several of us who are experiencing something that *looks* like hardware (disk) issues when using 7.0. Could this be related to the mouse freeze issue? Could some process be locking/grabbing the CPU at inopportune times and causing not only the freezing symptoms but also reads/writes problems? Can anyone else using 7.0 who hasn't already (especially those using ZFS) check his/her /var/log/messages for disk TIMEOUTs or other disk error messages? If this is widespread, I think the chances re slim that it is a hardware problem in every case. -Joe
