Hello Mauro/Andreas.
Unfortunately the patch I sent a few weeks ago introduces a _very_ infrequent timeout in
dvb_ca_en50221_io_writewhich I have to investigate. I don't like the idea of just increasing the timeout. But I am currently quite busy because I have a deadline for a university project to meet. So please don't sent the patch upstream until I have had a chance to look things over and correct the situation. Thanks and sorry for the inconvenience but I haven't run into this bug before and it's (at least on my machine) not so easy to trigger.
Ok.
I removed this patch from my submit queue on my -git trees locally. Please, let me know when you have a solution for this, in order to allow me to submit both patches.
Cheers,
Mauro

I still have this patch on my blacklist... It is applied just at the development repository. Any news?

Hi Mauro.
I am absolutely sorry that it's been ages since my last mail regarding this patch but life intervened in every way possible actually... and still does. To make matters worse, we (luckily) switched to dvb-s, so I am unfortunately no longer able make further tests if time would permit. :-(

I have used this patch on my machine for weeks after my last post and haven't had any trouble with it. Still there seems to be a hard to hit race condition now which would need further testing. Nevertheless IMHO the patch is a real improvement to the situation because before one could frequently run into issues... and now things work just fine most of the time.
Ok. I've added the patch on my queue for 2.6.29.
Cheers,
Mauro
