Hi, Horms

Hi Takebe-san,

thanks a lot for all your help with this problem. With a bit of luck we now have a solution.

I found that by porting kexec_disable_iosapic() to xen (which involved cut and paste only) and calling it from the right places, the serial port on the rx2620 works just fine in the second kernel.

The patch below applies on top of the latest xen-ia64-kexec release that I made. Let me know if you need a new release that incoporates this patch.

Wow, congratulations! Does kexeing from xen to xen work fine on both HP machine and Tiger?

Yes, both seem to now work fine for UP or SMP+maxcpus=1
