AEC6280 problem at boot
Hi everybody,
I have installed an
Acard AEC-6280M (Version 2.16)
PCI-to-IDE extension card into one of my mac's PCI slots.
However, when I boot Debian Linux 2.6.8-powerpc, the
following message shows up.
Wait for ready failed before probe !
hde: lost interrupt
(I am sorry that I cannot reproduce the error verbatim;
I have a huge number of Firewire-related error messages
so that dmesg skips the beginning of the boot messages.)
Does anybody know what the above lost interrupt/failure
means and how I can fix it?
Thanks a lot,
Kaspar
