Hi,
I would be most grateful for your advice.
One of our servers here has two Adaptec SCSI cards, a 2940 and a 2944 for the CCD array.
After I cvsuped to 3.2-STABLE yesterday from a 3.1-19990422-STABLE snapshot, only the first card on the PCI bus (the 2940) was detected on boot up.
I also observed this behaviour with 3.2-RELEASE boot floppies but not those from the last 3.1 snapshot on releng3.freebsd.org (3.1-19990505-STABLE) so I don't think it's some perculiarity of my kernel config.
I have now performed a make world from the the last 3.1 snapshot source and the card is being detected again.
I haven't managed to find anything in the release notes or errata for FreeBSD-3.2 about this and looking at LINT, the syntax hasn't changed as far as I can see; still a matter of specifying
controller ahc0
for any number of installed devices.
A problem with the new code commited in 3.2 or am I suffering from an acute case of pilot error?
The device probes from /var/log/messages are below in case they are of help.
TIA.
