2008-03-08 15:27:12 moa3333 description Binary package hint: linux-image pakcage: linux-image-2.6-amd64-generic hints: new kernel, b43 wifi driver, other reasons? Linux ubuntu 2.6.24-8-generic #1 SMP Thu Feb 14 20:13:27 UTC 2008 x86_64 GNU/Linux From time to time (every 10 to 100 minutes) the computer is frozen with no reason. It dosen't matter what i do when it freezes. With no reason, the image is frozen, the mouse is not responding, and i can't switch to any terminals either. I think the kernel is the problem. It hapends since i've updated to the latest alpha feisty from gutsy a few days ago (so upgrade to the kernel also) Other changes i made is installing the b43 proprietary driver for my wifi card (instead of the old ndiswrapper driver) - i do'nt know if it is because of this driver or not. http://linuxwireless.org/en/users/Drivers/b43 On my gutsy i only had the old nvidia driver buffer overflow in compiz, but it didnt made the kernel freeze (it slowed down the computer) so i guess it is not realted to this old bug. package: linux-image-2.6-amd64-generic Linux ubuntu 2.6.24-11-generic #1 SMP Fri Feb 29 21:26:31 UTC 2008 x86_64 GNU/Linux From time to time (every 10 to 100 minutes) the computer is frozen with no reason. It dosen't matter what i do when it freezes. With no reason, the image is frozen, the mouse is not responding, and i can't switch to any terminals either. It hapends since after updating to the latest alpha a few months ago. hints: the kernel, a module of the kernel (other than nvidia, ssb or b43), other reasons?

2008-11-24 13:27:31 Onkar Shinde linux-meta: statusexplanation I can confirm the bug. It is caused by some combination of modules b43, rfkill, rfkill_input. I have observed the problem in 2.6.25 kernel image available in repositories as well as unofficial 2.6.27 kernel image created by Michael Casadevall (NCommander/sonicmctails). I remember seeing this problem on some kernel image on hardy (probably 2.6.24). But since my ibook was not in working state for last few months prior to seeing the problem for first time and since I was eager to update to intrepid I didn't bother to debug it. Following are my observations on my ibook powerpc with broadcom 4306 chipset based wireless NIC. 1. The UI freezes randomly. At no point it returns to normal state. Most of the time the computer reboots automatically after some time. 2. If I am using console (Ctrl + Alt + F1), at the time of panic I see some messages related to either rfkill_input or b43_interrupt_handler. After that most of the time I get message that computer will reboot in 180 seconds and it actually does. 3. Yesterday I unloaded all the modules I have mentioned (modprobe -r) and I didn't get any UI freeze for more than four hours. I was connected to internet via wired NIC, watched movie using a DVD, had chats with friends, upgraded the machine with latest updates. No problems at all. I plan to blacklist the modules one by one so that I can identify which actually causes problem. Also If I get the kernel panic message, I will take a photo and attach to this bug. Hope this helps.
