With this patch when running `halt -p' my ia64 Tiger (using
tiger_defconfig) gets a stream of badnesses in iosapic_unregister_intr()
and then hangs up.
Unfortunately it all seems to happen after the serial port has been
disabled because nothing comes out. I set the console to a squitty font
and took a piccy. See
http://www.zip.com.au/~akpm/linux/patches/stuff/dsc02505.jpg
I guess it's an ia64 problem. I'll leave the patch in -mm for now.
