%That should be enough...

Hi Soren,

I am beginning to believe that the FIC mb is the problem.  My
IBM-DPTA-372050 is only half as fast (500MB bonnie)
as on the P2B (~10MB/s vs. ~19MB/s).  A Jan 11 kernel =

doesn't downgrade to PIO on the
IBM-DTTA-371440 as fast as this evenings -current with your
latest bits does, but eventually it gets there.

)(*&$#%$#  stupid magazine benchmarkers never actually test =

things like IO...  grrrrr....

Regards,
Russell
