Hi,
I'm trying to use VIA PATA with a compact flash. I'm consistently
getting "irq: nobody cared". Ideas?
It works fine with DMA-capable CF as master only.
Details:
IXP425 (ARM) little-endian
VT6421-based mini-PCI card
SATA ports (2) unconnected.
00:0d.0 RAID bus controller: VIA VT6421 IDE RAID Controller (rev 50)
00:0d.0 0104: 1106:3249 (rev 50)
Subsystem: 1106:3249

Expansion ROM at 48000000 [disabled] [size=64K]
Capabilities: [e0] Power Management version 2
Kernel driver in use: sata_via
Linux-2.6.29.4 or latest .30 .git.
gcc-4.3.3 (recent SVN).
Is putting a CF card into on-card slot (wired as slave) with no master
present a valid option?
The cards seem to work fine in USB reader and in CS5536-based system
(including UDMA with the DMA-able card + IDE-CF adapter).
