Sorry it took so long to reply it took awhile to run this test. It didn't cause a kernel panic for about 8 hours. df says only 623M of the available 7539M are used. Anyway this is with the latest checkin by Chris Mason with the patch you sent me. Also since you said you cann't reproduce this I thought it might be helpful to know the environment I'm doing testing on. I have been running bonnie++ on xubuntu 8.10 fully updated on vmware 6.5. No vmware tools are instead except for the mouse and video xorg drivers which come by default with ubuntu. I have two 8G prealloced virtual drives. The first one is where the xubuntu install is using ext2 for /boot and / and has a 512M swap partition. The second one is where I do all of the btrfs testing. I have it partitioned because I was experimenting with booting with btrfs as root so the partition btrfs is on has 7539M. The VM has 512M of RAM dedicated to it and is using one core of my Intel Core 2 Duo T7500 running at 2.2GHz. Lee ...
