Hmm, I may have solved the problem. As I mentioned above, I tried using Feisty and the problem seemed worse.
However, there was a message early in the boot phase that made me wonder... MP-BIOS bug: 8254 timer not connected to IO-APIC A bit of internet sleuthing led me to add "noapic" to the grub boot defaults. And, things seem to work just fine now - no hangups after a fairly extensive wringing-out yesterday and this morning. Right now I even have desktop effects enabled just to really try hard to break things! Interesting that some of the Internet discussion of the 8254 timer problem relate back to Dapper. I don't recall ever seeing the message in Dapper, but that was some time ago now. The message certainly never showed up in Edgy, though it may have been concealed by the splash. Anyway, I think I will close this bug report, and soldier optimistically on. -- [Edgy] - hangs, windows become unresponsive https://bugs.launchpad.net/bugs/98999 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
