I have 2 related questions:
1) What is exactly tagged command queueing?
I have a 2940UW and IBM DCAS34330 (UW) should they
support this feature? And how to enable it with
aic7xxx driver?
I run Linux 2.0.35 (SuSE 5.3) with my recompiled
2.0.35 kernel.
2) What does those messages significate:

This does not occur on Linux but on a SUN workstation which is
my NFS server, I know this list only talks about aic7xxx but the SUN
workstation have a 2940 too so ... Just forget my second question if it
must be.
Thanks in advance
