The hald media changed polling does really confuse things.
Noone knows why the delays are needed, but they give us access to the CD.
An udelay(50) will give reliable access to the drive, but there is still
one (or more) EH reset. The drive works without EH resets with udelay(100).

libata calls pci_request_regions to claim PCI BAR 0 - 5
pci_request_regions fails if one of the regions cant be claimed.
bar 5 has start == 0, __request_resource will fail.

Change the default for the built-in IDE on p610/p615/p630 from
ide to libata. libata has better error handling and the drive can
recover when hald does its CD media polling.

I'm sorry, how those 2 drivers can be equivalent?! The pata_winbond driver
is for VLB only, sl81c105 was for PCI only -- you certainly want to use
pata_sl82c105 (indeed better version of sl82c105 driver).

Sorry indeed -- I didn't realize PATA_WINBOND correscponds to
pata_sl82c105 (somewhat confusing, isn't it?).

I was under the impression that with your fixes these drivers
(sl82c105 and pata_sl82c105) are functionally equivalent.
Did I miss something (i.e. some patches)?

They're not yet equivalent. pata_sl82c105 supports all MWDMA modes,
sl82c105 still supports only MWDMA2.

Indeed and it seems that IDE core needs ->dma_mode to fix this.

Not really. It just needs the proper DMA timings to be set by adding the
missing speedproc() method (and also DMA timings possibly merged with PIO like
libata does generally -- except in this driver).

By "this driver" I meant pata_sl82c105 of course. :-)

By "this driver" I meant pata_sl82c105 of course. :-)

Does IDE sl82c105 need the same udelay() fix patch as done for
pata_winbond?

ACK the patch. I presume Paul will apply it, as its within his file
