Hello All,
I've spent the last couple of days attempting to get my Epia MII board to
boot from the onboard CF slot. I'm using coreboot v2 and have successfully
created a working kernel that will load from a CF card and detect both the
socket and the card.
The problem I have is that I have to boot the kernel with the irqpoll option
otherwise I get "qc timeout (cmd 0x91)" and "failed to IDENTIFY
(INIT_DEV_PARAMS failed, err_mask=0x4)" errors when the pata_pcmcia module
is inserted and the card is not accessible.
From what I have found this seems to suggest that the interrupts are not
being routed correctly and have to be polled instead. I'm happy to try and
fix this myself but I don't really know where to start. Are the interrupts
setup by the yenta-socket module or the pata_pcmcia module, which one should
I start to look at?
If somebody could point me in the right direction that would be great.
Thanks,
Robert
