mythtv-setup hangs on ioctl when adding HVR-2250

[kpyle@…]

When attempting to add a HVR-2250 via the "new capture card" option in mythtv-setup, the program shows a blank screen and becomes unresponsive. The HVR-2250 is working outside of mythtv and can tune and capture, as confirmed with gnutv from the dvbtools package.

OS is gentoo 2.6.32.8:

% emerge --info | head -n 1 Portage 2.1.7.16 (default/linux/amd64/10.0, gcc-4.3.4, glibc-2.10.1-r1, 2.6.32.8 x86_64)

This ticket can be closed. I've found the problem to related to suspend/resume where the driver does not properly recover. I've been able to add the card to mythtv. Sorry for the invalid report.

Thank you very much for reporting back.
