Dmesg output from kernel 2.6.29.1 with CPU stall

Latest working kernel version: 2.6.29 eventually boots, but the CPU stalls for 35 seconds while booting.

Earliest failing kernel version: 2.6.29, although I've had timeout issues as early as 2.6.26.

Distribution: Ubuntu 8.10

Problem Description: There is a weird CPU stall when probing IDE interfaces on boot. The stall lasts for about 35 seconds. The call trace sometimes is printed on the screen. In this case it was.

Steps to reproduce: Install 2.6.29 on a computer with the same hardware as me and reboot.
