Re: [parisc-linux] a pretty big change

= Hi all,
= 
= I have build a new kernel with the CVS version
= 19991205 and I get the following console output when I
= try to boot it on my 715/33:

If you'll place that kernel somewhere I can get it, I'll check
this, or you can.  Look into the kernel and/or System.map
for what's at 0xc004a078, which is inside a procedure which will
return to 0xc0112000.  It looks like a null (or small) pointer
dereference because we're trying to create a virtual mapping for address 0.
