Double Layer DVD problems may be kernel bug on heavily loaded systems
I tried to copy the 9.2 installation DVD to disk using two different DVD readers on running 9.1 systems, and they both failed with read errors part way through. Then I booted up the rescue system from the 9.2 DVD and copied the DVD to hard disk without any problems. To my mind this shows that the problem is caused by an interrupt related bug in the IDE driver. Just my $0.02 worth.

I'm wondering if what you say about the "interrupted related bug" caused what I saw twice yesterday. As a normal practice I backup my system to my second hard disk using rsysc. The load average was running at about 2.0 when the system froze. I had to reset the computer. So far I have been able to freeze the computer twice and both times I was doing heavy disk to disk copying using rsysc. This is on 9.2. -- SuSE Linux 9.2 (i586) ---- 2.6.8-24.3-default --- Tue 11/23/04 16:45 4:45pm up 9:14, 3 users, load average: 0.84, 0.77, 0.66

Are you running both drives off the same cable? I recently installed a second ATA drive onto the same cable as my primary drive, and then experienced frequent lockups under heavy loads. After switching the drive to a seperate cable, it has been rock solid, currently 39 days, where it was lucky to be a couple of hours before. This is on 8.1. Steve

Yes, I rsync most of the /* directories which are mounted on /dev/hda6 to a partition /dev/hdb7 mounted on /.snapshot. I have done this for the last 6 month under SuSE 8.2 without any lockups. This only happened under SuSE 9.2. Early this morning (4am) the cron script did rsync my system without locking up. Hopefully, it was a rare two time occurrence when I did a full rsync.
