Subject: Long timeout when booting >= 2.6.38

Hi all,

I have a strange hang/timeout when booting kernel 2.6.38 and newer. It 
hangs after a few initialization steps and then after 145 seconds, it 
continues to boot.

I bisected kernel and found that offensive revision is:

08ec0c58fb8a05d3191d5cb6f5d6f81adb419798
"x86: Improve TSC calibration using a delayed workqueue"

Older kernels before above revision work fine.

When passing acpi=off to kernel, the problem seems to disappear.

Dmesg output below where you can see the jump from 1.47 to 146.85.

The mainboard is an Asus M4A89GTD PRO/USB3 (latest BIOS revision).

Kind regards,
Chris

PS: the problem has also been reported to ubuntu where more hw 
information is attached.
