Just did a test, and the kernel is booting fine for me now, with
threadirqs and the wifi device.

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
** Description changed:
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.

Can you also see if this bug is resolved in the latest 3.13 stable

Hi there,
I can confirm that issue doesn't exist in v3.12 final. I have used both
the generic version of that kernel (from the ppa) and a recompiled
version with lowlatency params (which is right now the main kernel i am
using in 14.04)
The issue exists in the latest 3.13 kernel as well i.e. 3.13
It would be good to know if when using the threadirqs parameter is a
regression. If that is the case, we can bisect to identify the commit
that introduced this.
Can you test the following kernels with the threadirqs parameter enabled
and post back if any do not exhibit the bug:
v3.2 final: http:
I can confirm that booting linux-lowlatency with "nothreadirqs" boot
parameter worked, while having the wifi device attached.

Can you try booting the lowlatency kernel with the "nothreadirqs" boot
parameter?
