The pvrusb2 driver in kernel-2.6.27.3-39.fc10.x86_64 has a lockup issue which causes module operations to "stick", leaving (say) "modprobe -r" in "D" state, according to ps.

There is a fix upstream, which is in Linux 2.6.27.4

Meanwhile, the workaround is to load the module with the "initusbreset=0" option.  I did this by creating a new file, /etc/modprobe.d/pvrusb2, and adding a single line: "options pvrusb2 initusbreset=0" (no quotes).


Reproducible: Always

Steps to Reproduce:
1.Boot rawhide with Hauppauge WinTV PVR USB2 attached.
or
1.Hotplug Hauppauge WinTV PVR USB2.

Actual Results:  
pvrusb2 module fails to work -- attempt to "modprobe -r pvrusb2" leaves modprobe process in " D " state, udev gets frozen, module subsystem in kernel gets frozen, dogs living with cats, panic in the streets.


Expected Results:  
Expected operational Hauppauge WinTV PVR USB2

the pvrusb2 mailing list has a recent thread about this, culminating in a fix in kernel 2.6.27.4.
