Hi,

i have a setup with a ARM - CPU (Seagate Dockstar) and a DVB-T Stick with Philips TDA10046H. This stick works out of the box with each x86 Architecture. It use the ttusb_budget drive form the Kernel. If i scan a frequents i run into the Kernel Bug:

plugin:
[  37.810258] ttusb_cmd: failed, receive error -110
....
...
..
.
scan frequents:
[  133.624310] kernel BUG at arch/arm/mm/dma-mapping.c:425!


I have attachment a dmesg snipped with the interesting information.

How can i solve the problem?
