The attached patch rearranges the code so that the handler is installed before we setup the interrupt (so we have somebody to listen to the immediate interrupt), and it makes sure that we clear the event in the IRQ handler regardless of the state of the timer tick.

This patch indeed solves the problem. The board boots fine. Great work!
since this driver is new in 2.6.24, perhaps we should apply this fix to v2.6.24?
Ingo, Jordan,
I have written the two minor patches we were talking about in previous mail. The first one fixes the input clock from 32000 to 32768 Hz, and the second one adds an "mfgptfix" boot parameter to enable the workaround in order to fix a regression on motherboards with a broken BIOS on which 2.6.24-rc8 does not boot anymore whether mfgpt timers are enabled or not.
Jordan, if you think you'll push your changes for 2.6.24, feel free to merge this patch with your work.
Both patches will be sent as a reply to this mail.
Regards,
Willy
