Three Observatins with 6.2.35 on Linux 2.4.20

[Frank Strauss]

Hi!

Like some other people we recognized messages raised by PCI interrupts
signalling parity errors on the PCI bus (that are not necessarily
caused by the SCSI subsystem). So we moved to 6.2.35, which is
supposed to turn off these messages after 10 messages have been
issued. But what in fact happens is, that it is *not* turned off, but
every such message is just followed by additional lines that just say
it would be turned off now (see below).

Another observation is that the message "DV failed to configure
device.  Please file a bug report against this driver." appears.
Since I don't even know what domain validation is, I'm hereby just
doing what this messages says. :-) So far, I'm just ignoring it and
I may turn DV off through the appropriate command line option.

Third observation: When I first chose CONFIG_AIC7XXX_BUILD_FIRMWARE I
could not build it. I assume this is because my flex and bison are
quite new (2.5.31, 1.875a) and I had similar problems in another
project where I use flex and bison. There it was due to YY_* macros
that have changed. Sorry, I've no further information handy. I just
switched to not building the firmware and that works fine, of course.
