Is that branch >> confirmed to work with my chipset? Yes. I'd also strongly recommend consideration of patches #23 and #26 from here: http://sweaglesw.net/~djwong/docs/sas_ata-patches/ I create my kernel tree by cloning the linux-2.6 git tree and then applying scsi-misc-2.6, scsi-rc-fixes-2.6 and aic94xx-sas-2.6 patches atop that. And then the giant long slew of patches atop *that*. >> I have also tried to compile the latest rc of the 2.6.20 kernel and >> loaded up the aic94xx driver + firmware.

Ideally that message would have printed something less cryptic, such as "SATA device found but not supported in this driver!", but that's water under the bridge at this point. > it was too old) showed the same problems (tmf timeouts). Then The TMF timeout problems (and several other bugs) were fixed in v18 of the sequencer firmware blob. Alexis, Ed, and Gilbert are currently working to have the firmware blob posted on Adaptec's web site. I think the sequencer is up to v28 now? (Vaporware, I know, but hopefully we can nip this one in the bud soon.) > Luben Tuikov sent me a version of his driver with a "use_msi" > related fix in it. My 48300 has been rock solid since.

I'm not certain that I'm completely aware of the failures that you're seeing with the driver. Can you send me the BIOS firmware level, the sequencer version (probably v17 since that's the only one that I know of that's available on the 'net), and a dmesg output? > I have encouraged people to talk amongst themselves about the > use_msi patch, but I don't believe that I should be reverse > engineering that patch.

There is a known bug where one needs to kick one of the CHIMINTEN bits if a certain flag is set, though none of the IBM boxes require MSI (and at the moment it isn't working anyway...). >> 2. http://www.jimmy.co.at/weblog/?p=71 Egad.
