Subject: Promise SATAII 150 TX (PDC 20579) & PATA/SATA port problem

Hi,

I'm using the linux 2.6.13 (from http://www.linux-mips.org) containing the
libata patch (2.6.13-rc7-libata1.patch.bz2) on an AMD DBAu1550 (mips32).
I've connected a HDD to the pata port of my PDC 20579 controller.
Unfortunately, it doesn't work. Here a part of the boot messages:

...

I've try to connect a HDD on a SATA port and the problem still appears
:(. More when I try the 2.6.10 kernel with the corresponding libata
patch it, works !

Does somebody have such a behaviour ?
Please help me ! What can I do to make the kernel2.6.13 works with my
promise controller ?

Thanks
David

Hi, David. I think I have the same problem with a similar card, the SATA150
TX2plus. The sata_promise module sees the SATA ports, but not the PATA port.

Promise made up a driver called pdc-ultra (not based o ftlib.o) that worked with
2.4 kernels (I could see the PATA drive as a SCSI drive), but it spits back
"unresolved symbols" errors with 2.6. Promise is useless for tech support on
this.

Jeff Garzik says something on the libata website about a patch for preliminary
support of PATA on Promise SATA, but I haven't tried it out.
