Never had any cache/memory/etc problems. Mitsumi 2x CDrom (no model no, sorry, but can pull it apart and look if you insist). >Description: Under 2.1.0-R and 2.1.5-R, the mitsumi CDrom runs perfectly. Under 2.2-961014-SNAP, it struggles along with numerous read timeouts and retries; short reads (i.e. of directories, etc) appear OK, longer reads (of more than 15-20K) start failing. Degradation is *not* graceful; once it has started missing reads, it appears to miss more and more. Timeouts, etc, in the source code for the two distributions are all set to the same values. NB: The severity and priority of this problem depend on your point of view :) >How-To-Repeat: Install 2.2-961014-SNAP, then try to read a long file from CD. It is, of course, possible that one needs precisely my machine to do so; I haven't been able to convince any of my friends to try the SNAP, and so cannot be sure. >Fix: Reinstall 2.1.5-R (via the ether card, since the CD won't work :) Cheers, Mike. >Audit-Trail: >Unformatted:
