I am having the same problem on a Dell XPS 1210 notebook running Edgy (2.6.17-10-generic). The system locks up only when booting with the ipw3945 kill switch turned on.
Can we expect an official fix for this (on 2.6.17-10-generic) anytime in the near future? -- CPU soft lockup during bootup https://launchpad.net/bugs/63418 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
