1. this is about v4l-dvb linux kernel driver not about distros like ubuntu.
state kernel (v4l-dvb hg) version pls. 

2. searching the list-archives before opening new threads is mandatory, 
ive reported this issue about a year ago. thx for the confirmation.

use SysReq keys and report where the kernel freezes (stacktrace), 
if You want to have boot fixed. i dont have got this card anymore.

this card uses a unknown? pci-bridge and a sharp tuner. 
dexatek and sharp refused to release programming information 
about their products to us, so creating a driver would require 
reverse engineering with a pci-extender and i2c sniffing.

since there are many supported cards available for only 5-10 bucks more 
this is an uneconomical effort, so throw this card back to the 
seller until dexatek and sharp provide support to linux developers.

sorry

tom
