Problem building 2.6.14-rc4-rt10. The only change to my config file
was to turn on a few options for Mac disks. I doubt that's involved
with this. I will send the .config file if requested.
Thanks for looking after this SCSI error. I'm anxious to see that go away.
Cheers,
Mark

I'm sorry, but I seem to have been added to the CC list for this thread
a while back, and I don't remember why. I haven't seen anything relevant
to me recently, so please drop me from the CC list. Thanks.

Thanks Ingo. Sorry for being such a putz! ;-)
2.6.14-rc4-rt11 is up and running. No SCSI errors. No xruns as of yet.
Thanks very much,
Mark
