After reverting yesterday's glibc packages, I noticed my system freezing after several hours of "mostly idle" (actually, only azureus active). After the last one, I noticed the following in /var/log/messages: Oct 28 19:17:22 localhost kernel: Uhhuh. NMI received. Dazed and confused, but trying to continue Oct 28 19:17:22 localhost kernel: You probably have a hardware problem with your RAM chips I ran memtest86+ for about 14 hours, but detected nothing. This is running on 4 week old Thinkpad X60. Any thoughts? tom -- Tom London -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
