Are you able to trigger this timeout? Is yes, how?

Imho it cannot happen anymore (because of [1]) unless the hardware is
broken. Even with nonexistent devices there should be an I2C irq.

Anyway, it is a good idea to add this timeout protection.
I didn't see such a timeout.
If it cannot happen under normal circumstances you should replace
DEB_I2C by printk.
I am getting swamped by this message. It occurs every second.
My HW is an 1.3 FSC DVB-C + Cinergy T2 + Cinergy T-1200.

Anything I can do to debug this ?

Regards

Dominik
