Hi!
i am conmfiguring an Ultra5 to play with, and i wanted to add a better IDE controller to attach a couple of 120gb UDMA5 drives, and use it as a file server.

Well, i have a Promise IDE controller using the PDC20271 chip (yes, it is a raid controller but i just want to use it a s a normal IDE controller), so i compiled the pdc20xx_new driver as a module.

Result:
the pdc20xx_new crashes with a oops, the machine does not hang, but the controller does and i need reboot to try again.

the pdc20xx_old does not support this chip so it does not boot.

So i decided to reocmpile my kernel adding support for the device built-in instead as a module, and now it works like a charm....

I hope this can help someone.

Can you post more info on the crash, including all output related to the crash that you see on the screen?

Making it work may include accessing the firmware on the card which might mean it tries to load the firmware into ram on the Ultra. It might work if you remove the chip. I've got a Promise Ultra100 card that I might be willing to mess with on my Ultra AXe. It just has solaris9 on it right now.

I'm about to embark on this same journey, only I'm using a PDC20262 i.e. Ultra66 with an Ultra10. The kernel is compiling right now, and I'll test it out as soon as it's done.

P.S. If anyone knows the maximum size IDE drive this controller allows, please let me know, I can't find too much info on it.

Well, it works! Seems to work well too, just needs to be tested out a few more days untill I trust any of my important data to it.
I built the drivers into the kernel instead of modules, btw.

Out of curiosity, could your post the output of lspci and lspci -n ?
