Hopefully someone from the sparc or sparc64 team at Debian can look
into this.  I am going on business travel for 4 days so will be away
from any Debian/SPARC machines for a while.

These are the questions which need to be answered:

 * do other people running debian sparc finding the problem, using the
recipe I mentioned in previous email?

 * Is it 2.2.9 specific? Sun4u specific?

 * get strace output as Tom suggests

 * shouldn't we notify the Sparc/Linux folks?
