I used to run 2.5.x as my laptop has the Intel ICH3M chips in it, and on the plain 2.4.x it would fail during boot claiming "resource collisions". In 2.4.19-ac4 or thereabouts it seemed to have been fixed the the ac-releases, and I ran happily with 2.4 again. After seeing a lot of IDE rearrangements lately I thought it was time for a YANK (Yet Another New Kernel), and the ICH3M seems unhappy again about resource collisions:
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ICH3M: IDE controller at PCI slot 00:1f.1 PCI: Device 00:1f.1 not available because of resource collisions PCI: Assigned IRQ 11 for device 00:1f.1 ICH3M: Not fully BIOS configured! ICH3M: chipset revision 2 ICH3M: not 100% native mode: will probe irqs later ide0: BM-DMA at 0x4440-0x4447, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0x4448-0x444f, BIOS settings: hdc:DMA, hdd:pio hda: TOSHIBA MK4019GAX, ATA DISK drive hdc: SD-R2102, ATAPI CD/DVD-ROM drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 hda: host protected area => 1 hda: 78140160 sectors (40008 MB), CHS=5168/240/63, UDMA(100) hdc: ATAPI 24X DVD-ROM CD-R/RW drive, 2048kB Cache, DMA Uniform CD-ROM driver Revision: 3.12 Partition check: hda: hda1 hda2 hda3
However, unlike back in 2.4.18, this time I can run hdparm and get it to run in UDMA mode (instead of the default PIO mode) and get the performance back.
Relevant bits of the .config:
