Problem with 2.4.21-pre1 Promise PDC20276

Hi.

i have PDC20276 BIOS ver 2.20.1020.13 promise device

And with kernel 2.4.21-pre1 the kernel recognize correctly the promise card but not the IDE devices. With 2.4.20 it work correctly using the same .config file.

--------- 2.4.21-pre1 -----------------
PDC20276: IDE controller at PCI slot 00:0f.0
PDC20276: chipset revision 1
PDC20276: not 100% native mode: will probe irqs later
PDC20276: neither IDE port enabled (BIOS)

I try to load as kernel module too and pdc202xx_new.o give me the same error. /proc/ide/pdcnew
MBFastTrak 133 Lite Chipset.

---------- 2.4.20 -----------
PDC20276: IDE controller on PCI bus 00 dev 78
