2.6.19-git3 panics on boot - ata_piix/PCI related

2.6.19-git3 panics on boot - ata_piix/PCI related

[Alessandro Suardi]

FC6-latest running on a Latitude D610, SATA hard disk;
 2.6.19 is okay, kernel built with oldconfig from the
 known-working setup fails to boot not recognizing the
 root partition, which is due to ata_piix not loading due
 to a PCI I/O reserve error.
Happens both with and without CONFIG_SYSFS_DEPRECATED
 (I first had it to N then thought it might have had something
 to do with the boot error so I rebuilt with Y - no change).

Messages hand-copied from the screen on the 2nd try:

Loading ata_piix.ko module
ata_piix 0000:00:1f.2: MAP [ P0 P2 IDE IDE ]

This is what is in the dmesg ring of 2.6.19:

Same failure is also in 2.6.19-git4...

I'll download -git1 and -git2 to see which one broke my setup first.

Thats the PCI updates - you need the matching fix to libata-sff where it
tries to reserve stuff it shouldn't.

Thanks Alan. Indeed -git1 is where stuff breaks for me.
I'll watch out for when libata-sff gets fixed in the -git
 snapshots and will then report back.
