Odd,

I am hitting this on my rx2620, rx6600 and rx2600 (i.e. everywhere I
have tried it) and the bisection is showing that it appears to have been
broken before -rc1.


It appears to have something to do with grabbing the kernel args.  The
panic happens here:

0xa0000001007f1511 is in setup_arch (arch/ia64/kernel/setup.c:570).
565
566             /* enable IA-64 Machine Check Abort Handling unless disabled
*/
567             if (!nomca)
568                     ia64_mca_init();
569
570             platform_setup(cmdline_p);
571             paging_init();
572     }


If it is working for others I am wondering if the version of elilo makes
a difference.  I am using RHEL5 as my base system.  I might try grabbing
elilo from upstream or from another release and see if that makes a
difference.

Bisection almost done, should know what commit triggered this soon.  I
tried reverting a couple seemingly obvious patches but didn't find it
that way.
