Hi, I have tested the mainline kernel and also need to post a correction - this issue also arises in both the mainline and 3.14-rc2 just at a different stage to the earlier kernels
In the earlier kernels that i checked , the kernel would panic on boot i.e. before getting to the X login screen. On both the 3.13 mainline and 3.14-rc2, the kernel panics when logging in- it seems that it locks up when compositing is switched on but am not sure. I can't test this completely in 3.14 as i cant get fglrx to compile against it (i see the lockup happening when logging in). I am able to boot and log into the kde session with compositing enabled on 3.13 mainline when i put in nothreadirq as a param so not too different from the earlier kernels Bharat -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1279081 Title: linux freezes with threadirqs parameter when rt73usb is loaded Status in “linux” package in Ubuntu: Confirmed Bug description: While my usb wifi device is connected, the kernel will freeze while booting. I can boot into recovery mode, but freeze happens as soon as I enable networking. I can boot and login fine without the device attached. As soon as I plug it in, the system freezes.
