I am not sure if this is related, but 2.3.3 doesn't boot on my Acer M5229 + IBM DTTA+351010. It detects the disks fine, but cannot find init.
2.2.8 + your big IDE patch works fine. So far I haven't tracked down the cause. I first suspected a egcs 1.1 aliasing bug, but recompiling with -fno-string-aliasing didn't help. The geometries in the 2.3.3 boot screen look correct.
Output from the working 2.2.8+patch kernel:
Uniform Multi-Platform E-IDE driver Revision: 6.19 ALI15X3: IDE controller on PCI bus 00 dev 78 ALI15X3: not 100% native mode: will probe irqs later ide0: BM-DMA at 0xb800-0xb807, BIOS settings: hda:DMA, hdb:pio ide1: BM-DMA at 0xb808-0xb80f, BIOS settings: hdc:pio, hdd:pio hda: IBM-DTTA-351010, ATA DISK drive ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 hda: IBM-DTTA-351010, 9671MB w/466kB Cache, CHS=1232/255/63, UDMA(33)
Any clues on how to fix it?
Recompiling 2.3.3 without ALI 15x3 support didn't help.
