It doesn't happen with a GENERIC kernel; for me
it didn't start happening until this last build.  It's maddening as this now 
means that it will take 16 hours to update my entire source tree once
a month.

 *    reliably do a sup -a in any form.
 *    
 *    ...anyone else see this?
 * 
 * it's been reported a few times,... i did myself in october or
 * november last year.  i have _NO_ idea what causes it.  i now
 * run my ppp link at 19200 because of this (even though i have
 * fixed our zs driver to allow 76800 :-( ).
 * 
 * i think it happened _after_ november 3.  i looked at all the
 * changes from the kernel from november 3 to november 18 (i think
 * it was 18), which is after i first notied it, and i didn't see
 * anything that would cause it.
 * 
 * (for reference, i was using an ELC until a few days ago.  it is
 * now an IPX -- haven't noticed a problem but i haven't tried any
 * higher than 19200 still).
