Bug#361214: RED state exception crashes on sparc64 SMP

[Jurij Smakov <jurij@wooyd.org>]

Hi Blars,

According to Fabio Massimo Di Nitto, who is the Ubuntu sparc kernel 
maintainer, quite a lot of fixes went into the sparc64 SMP code recently, 
so the recent upstream snapshot is worth to try. I have built a 2.6.17-rc2 
kernel from today's snapshot of Linus' git tree. It boots fine on my 
Ultra 60, it would be great if you could play with it to see if you can 
make it to crash. The kernel is at

http://www.wooyd.org/debian/kernels/linux-image-2.6.17-rc2-sparc64-smp_2.6.17-rc2-1_sparc.deb

Make sure that you use yaird to generate the initrd as initramfs-tools 
currently appear to be broken on sparc (at least for me, didn't have time 
to investigate yet). If it still crashes, I'll try to build a custom 
kernel which would produce more debugging information.

Thanks,
