Same problem with a Fujitsu-Siemens Amilo Si 1520-23, 2.6.17-10-generic. The modified ipw3945.ko fixed the boot, but I lost sound afterwards. Restoring to the original ipw3945.ko did not help.
And the frequency kill switch is unresponsive during boot. If I forget to set it off after turning off the computer, I have to boot WinXP and turn wifi on there before Edgy is able to boot. -- 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
