Thanks for your attention; actually, running the memcheck was one of the first things I tried: it ran overnight without any problems. I also checked the CD MD5SUM, burned at only 4x, and checked the CD for defects from the menu option -- and all was fine.
Very important note: this system ran Edgy fine. Between Edgy and Gusty something must have changed that it's causing these problems. I am now recompiling the Ubuntu kernel source, setting the target for K7, and turning off some of the newer features like the "tickless kernel". I'll keep you posted. -- Xorg crashes very frequently https://bugs.launchpad.net/bugs/149639 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
