I am running Linux kernel 2.0.33 with the aic7xxx patch 5.0.5/3.2.2
with an Adaptec 2940U adapter.
I was running an older version of the driver and had problems, so I
got the newer driver to see if the problems would go away, but they
did not.
when I boot, dmesg reports the following:
[BEGIN DMESG RE:AIC]

When I back up the system I get the following errors:

In looking at the code in aic7xxx.c, I suspect that maybe I should
uncomment:
/* #define AIC7XXX_TAGGED_QUEUEING_BY_DEVICE */
then change:
adapter_tag_info_t aic7xxx_tag_info[] =
{
{DEFAULT_TAG_COMMANDS},
{{4, 0, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, -1, 4, 4, 4}},
{DEFAULT_TAG_COMMANDS},
{{-1, 16, 4, -1, 16, 4, 4, 4, 127, 4, 4, 4, 4, 4, 4, 4}}
};
to something like:
adapter_tag_info_t aic7xxx_tag_info[] =
{
{{-1, 0, 0, -1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}},
{{4, 0, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, -1, 4, 4, 4}},
{DEFAULT_TAG_COMMANDS},
{{-1, 16, 4, -1, 16, 4, 4, 4, 127, 4, 4, 4, 4, 4, 4, 4}}
};
but I hesitate to take such steps without knowing if I am on the right
track, and knowing what the ramifications might be, and knowing if
this a known problem with this particular configuration.
I am willing to change hardware if that might be a more elegant
solution, but I am not clear, from the info that I see, as to which
device is really causing the problems.
Thank you for your patience in reading through all of this stuff, and
thank you in advance for your help and suggestions.
