But apart from that if you just connected your PC to a TV I also wouldn't recommend using an interlaced resolution in the first place.
See those resolutions only exists for backward compatibility with analog hardware.
I think we would just disable those modes instead of searching for the bug.

I guessed so.
The GPU is a Radeon HD5870, and the screen is an old Telefunken TV (TLFK22LEDPVR1).
Since my real display got into repair I used this TV meanwhile, and to my surprise it froze the system.

Hi Alberto,
well what hardware do you have?
Interlaced resolutions are not used any more on modern hardware, so they
are not well tested.
