[pvrusb2] pvrusb2 and Fedora 11 - Audio cut after sometime of capturing

Tue Aug 18 19:18:12 CDT 2009

I tried a couple different vanilla kernels from kernel.org, but so far 
no improvement. Here the kernels installed:
   kernel 2.6.30.4: Could not boot the machine with this one (got some 
kernel panic message)
   kernel 2.6.27.29: Could not boot the machine with this one either.
   kernel 2.6.29.6: Machine works fine but still have the same issue 
(audio cut after some time while capturing from 29xxx) . This is the 
same issue as running the F11 kernel 2.6.29.6-213.fc11.i686.PAE

    Here the procedure used to compile the vanilla kernels (in case I'm 
doing something wrong):
   1- copied the F11 kernel config to my kernel source dir:
          # cp /boot/config-2.6.29.6-213.fc11.i686.PAE .config
   2- Run
          # make oldconfig
       This asked a couple of questions depending which kernel was 
compiling. I choose all defaults.
   3- Compile and install the kernel:
          # make
          # make modules_install
          # make install

Thanks
Alejandro
