It's a self-built kernel, but without modification.
I neglected to include a modules listing in the bug report. Here are
those myst likely to be involved:
ide_generic 1472 0
sis5513 16776 1
hpt366 22788 2
ide_disk 19264 5 hpt366
ide_core 138776 5
usb_storage,ide_generic,sis5513,hpt366,ide_disk
sd_mod 21632 0
ata_piix 8132 0
libata 41348 1 ata_piix
scsi_mod 124620 3 usb_storage,sd_mod,libata
unix 28592 170
I wonder if your ide chipset got correctly detected (aparently), and if dma
and other such parameters are identic.
The sis5513 is plausible, I know it is used for earlier SiS chipsets.
Here are the kernel messages I think relevant:
PCI: Probing PCI hardware (bus 00)
Uncovering SIS963 that hid as a SIS503 (compatible=0)
Enabling SiS 96x SMBus.
ACPI: PCI Interrupt Routing Table [\_SB_.PCI0._PRT]
I asked because another guy (with a piix chipset though), was claiming that
his chipset was not detected, and thus that dma was not activated.
I clean forgot to explicitly affirm that it has DMA on:
kowari:~# hdparm /dev/hda
/dev/hda:
multcount = 0 (off)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 16383/255/63, sectors = 234439535, start = 0

I prefer u1 c1 but generally those make little difference.
kowari:~# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 92 MB in 3.04 seconds = 30.23 MB/sec
kowari:~# hdparm -t /dev/hda{,,}
/dev/hda:
Timing buffered disk reads: 112 MB in 3.01 seconds = 37.17 MB/sec
/dev/hda:
Timing buffered disk reads: 108 MB in 3.05 seconds = 35.43 MB/sec
/dev/hda:
Timing buffered disk reads: 108 MB in 3.02 seconds = 35.73 MB/sec
