I sent an email about this on 7/28, but didn't get a reply (but you sent
more info than I did):

  I tried upgrading to 2.4.7+IA64-010726, but when I did that, "init" dies:
    init[1]: IA-64 Illegal operation fault 0
  [...]
    Kernel panic: Attempted to kill init!

The 2.4.5 kernel boots with the 6/26 patches, but I'd like to run a newer
kernel too :-)
