Feisty Herd 3, BUG: soft lockup on CPU#0

[Guido]

After instalation feisty-desktop-i386 Herd 3 system always freeze during the first boot with this message:
[ 22.648000] BUG: soft lockup detected on CPU#0!

[Guido (vit-kotacka)]

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.

[Guido (vit-kotacka)]

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.

[Robert McMeekin (rrm3)]

Phillip, my problem has been fixed in Herd 4.

[Guido (vit-kotacka)]

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".

[Joseph Maillardet (jokx)]

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