My guess is that you are using a B1 processor. ( Revision 2 )

You HAVE to use kernel 2.4.4 in my experience to stop the panics.

2.5.5 is good on B3's and C0's I ssume 2.4.7 would be fine here too.

I've just got my first (secondhand) IA64 box, and I'm trying to get 2.4.7
running so port some other kernel code (loadable security modules) to the
IA64.

Taking a vanilla 2.4.7, applying the 0726 patch (#2) and the suggested
compiler fix as I'm using stock RedHat 7.1, I get...
