Hi,

	I am using alot of tuners Leadtek DTV1800H under Linux, minimum 5 devices per one PC with kernel 2.6.37.4. I discovered bug which I can se very often but not always. When device tuner is reseted there is not enough time to do all needed stuff and sometimes (randomly) kernel show this message:

[  821.369647] cx88[0]/1: IRQ loop detected, disabling interrupts

Patch is again very simple, we need to adjust time in reset function after cx_clear and cx_set calls from 50 to 75 us. I tested this patch on 4 PC with similar problems and all are without this issue.
