Just today (18 Sept/06) installed Edgy Knot 3, the same "soft lockup" message on my AMD Opteron box, alternating between CPU#0 and CPU#1. Also, usplash segfaults, and in fact there is no splash screen on boot or on shutdown/reboot; the latter needs using the shutdown/reboot button.
FWIW, I use the same kernel version 2.6.17-7 with Gentoo, no problem there. -- BUG: soft lockup detected on CPU#0! https://launchpad.net/bugs/60053 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
