Sil3112 SATARaid PCI Controller Card

[Daniel Henninger <jadestorm nc rr com>]

Hi folk!

I suspect I am kind of doomed here, so I'm trying to see if anyone  
has any suggestions.  I have a Silicon Image 3112 SATARaid PCI  
controller card.  (or at least that's what it announces itself as and  
I vaguely recall that being the name that was on it when I bought  
it.. was a while ago.. it's non-trivial for me to just shut my  
machine down and look)  I have a Seagate SATA drive connected to it.   
I don't actually use the raid functionality of the card, just  
basically use it as a means to connecting an SATA drive to my machine.

So I've been using this under RHEL3 for quite some time now and have  
had no problems.  I tried to upgrade to RHEL4 over the weekend and my  
drive was not recognized.  In the boot output I'd swear I can see it  
being recognized, but then it sees no drive what-so-ever.  (drive  
comes up as hde)  After some chatting on ##linux and various attempts  
to get it happy, I ended up giving up for now and stayed with RHEL3.

I tried downloading a driver disk from Silicon Image's site and  
Anaconda didn't recognize the driver disk.  Or rather, i said it  
couldn't find anything usable on there.  The site explicitly says the  
driver is for RHEL4.  I also tried a firmware update on the card  
which helped nothing.

Not entirely sure what to try at this point.  I see smatterings of  
reports about the combo of this card and some seagate drives causing  
problems for each other.  (but then why is it working with RHEL3?)  I  
also see smatterings of how it "works under other distributions".  I  
also see some talk about how it'll lock up the machine and that is  
not happening to me.

Any suggestions?  I've exhausted my ideas for how to take care of the  
issue and am happily back down to RHEL3 for the moment, but I'd still  
like to upgrade if possible.  Thanks!  (BTW, I had one thought if  
simply running up and getting a new card by Adaptec.. except I soon  
found out that the card in question has the same chipset as my card)
