Disabling a wireless devices in the BIOS solved the problem. System boots on a graphic sign-on.

After re-enabling wifi in BIOS system still works. The error doesn't appear anymore.

The error returned after yesterdays update. The system always freezes after checking a filesystem. I must disable a wireless card in order to sign into the system as a normal user.

Upgraded to v1.2.0 of ipw3945, which I believe fixes this problem. Should be available within the next week.

Confirming this affects a Toshiba A105-S2101. Disabling wireless at boot has no effect. This system does not use ipw3945.

Hi,

i own a lenovo 3000 n100 with a ipw3945 card and the bug is still here with linux-image-2.6.20-8.14-generic (with ipw3945 1.2.0mp says dmesg)

In fact the bug only appear when i boot with wifi kill switch on (so when i turn off wifi)

Robert McMeekin, can you raise a separate bug. In this bug report please give the output from lspci -v, lsmod and dmesg. Any other information you have regarding your wireless card would also be useful.

Phillip, my problem has been fixed in Herd 4.

Problem is fixed on Dell D820 with 2.6.20-8-generic kernel now. I have WiFi enabled in the BIOS and "Radio Frequency Kill Switch is On".

The problem is always here for me with Feisty final release up-to-date on a desktop computer without any wireless devices :-(
