It's using the amr(4) driver. Ok, next question... Is anyone who is having these problems NOT using UFS2? I've been slowly changing one major-ish thing at a time on the machine I'm having problems on and then seeing if I could wedge processes afterwards. Until now wedging them has been trivial, no more than 10 minutes' worth of running find's. Since shifting all the disk partitions on the machine from UFS2 to UFS1 two nights ago I haven't been able to wedge anything. It even survived a full backup which it hasn't done for months now. I'll keep testing for a while to make sure but at this point if a similar change is easy for any of the other people reporting this problem it might be worth giving it a try... If I'm not successful wedging anything after a couple of days I'll try moving one of the partitions back to UFS2 and see if I start having problems again. -- Ken Smith - From there to here, from here to | kensmith@cse.buffalo.edu there, funny things are everywhere. | - Theodore Geisel |
