Philip and Bartlomiej,

I've been tracking an almost identical problem on my IA64 platform with 
a bk pull that is about a month old. 

I tracked it down to a duplicate vector request of 0x38 = 56 by the 
mmtimer -- take a look at /proc/interrupts, /proc/ioports, /proc/iomem 
and see if anything has requested the specific area that your CD is 
trying to get.

Interrupts and iomem seem pretty much the same, but ioports looks like
the following:
