I just replaced an Adaptec 19160 (which has been working fine for years in
this setup) with a 39160, and added a extra disk to the B channel on the
39160. The 39160 has the latest BIOS revision, 3.10.0, and is left at its
default settings.
With an August 24th kernel I am now seeing these:
Sep 11 09:28:13 lizzy kernel: ahc1: Timedout SCB already complete. Interrupts
may not be functioning.

I am using what looks like a decent, undamaged Ultra160-LVD/SE cable for the B
controller, ahc1, and I have never had any problems with the other cable on
the 19160. The 39160 has supposedly never been used. The motherboard is an
Asus CUBX.
What could be wrong? Could the 39160 or the B cable be faulty?
Any help appreciated.
Thanks,
