[uClinux-dev] 2.4.31-uc0 request_irq failure

	I am trying the 2.4.31-uc0 kernel but it seems that is a bit
different managing interrupts than 2.4.24-uc0 that I had been using. The
request_irq function fails and indicates that there is no dev_id.

The output is:

COLDFIRE port done by Greg Ungerer, gerg at snapgear.com

Bad boy: ColdFire Timer (at 0x00033010) called request_irq without a
Calibrating delay loop... 42.39 BogoMIPS

The problem persist with my own drivers... I don´t know if there was an
important improvement in the kernel tree regarding to the treatment of
the interrupts that needs to reprogram all drivers to support it. It
would be right? 

My system
Platform: Coldfire M5282
Kernel: 2.4.31-uc0
Distro: 20040218
