I don't know who you talked to, but it couldn't have been anyone in the 
technical support department.

We are aware of a problem in the 2.2 kernel which can result in an overflow 
of the TSS stack due to too many interrupts occuring quickly.  Usually this
is caused by high speed serial i/o -- a UUCP connection at 9600 baud can 
cause this -- and the problem has been fixed in version 2.3.
