Kernel Question

[Robert Sinland <rsinland@means.net>]

  As I mentioned in a previous post, I'm having some problems
with PPP under the 2.2.5   kernel.
   Here is a demsg after boot
Detected scsi removable disk sda at scsi0, channel 0, id 6, lun 0

   Is this telling me to update my rc scripts, ppp deamon or setserial?
As it stands by watching tail -f /var/log/messages I am  actually
connectiing to my ISP,
I just can't do anything...so I'm assuming ppp is broken somewhere.  Works
fine under
2.0.29 though.  Is the 2.2.x kernel family worth the hassle?
Thanks for any advice.
