2.6-test3 compusa USB optical mouse
I normally use Logitech optical USB mice in Linux. I bought a "CompUSA Optical USB Notebook Mouse" for $14 and the following happens in dmesg in kernel-2.6.0-test3.
Known bug? Should I Bugzilla this?

You don't state whether the mouse actually works.
Assuming it doesn't, yes, please bugzilla it, or bug the folks at [email protected]

This is probably due to userspace performing a system call while the CPU has interrupts disabled. Privileged apps can do this - the X server and hwclock are two examples.
Longer-term we probably need to remove the irqs_disabled() test from __might_sleep().
