Hi kerry and all. I decided to try switching to sid because i have been ruuning woody successfully (with 2.4.18 by the way) for quite some time. but woody is no longer getting upgrades of any significance as it is being prepared for release. I maybe would have been wiser to wait until woody was released to switch to sid. However, I do agree with you; this is in part a kernel problem, or zipspeak wouldn't be having hdc working fine (haven't tried that with scsi emulation on zipspeak). But I'm running with everything built into the kernel not modules, and I'm having trouble figuring out what more to do to diagnose the source of the problems. I have written to the debian list to try to pin down what might have done this, so am exploring all fronts. As for which distribution to use, I would be going nuts if I had stayed with potato all this time. but you are absolutely right; that is a very individual decision. I also have had no trouble with 2.4.x kernels, but i no some people have had lots of problems. If you don't really need to upgrade your distribution or your kernel, there's no reason why you should do so--unless you just happen to be one of the people that enjoys exploring new kinds of things. I am one of those people. And i do realize that this can increase the possibility of something breaking. I don't mind that--at least if I can figure out what it is and fix it.
