I am running a Sparc64 Ultra5 with IDE [insert flame here] which uses a
CMD646 PCI controller, and since at least 2.5.20 it has not booted. I
currently run 2.5.13, which boots and runs fine, and all is well with 2.4
series.
I have tried current bk, with IDE 94,95, and 96 applied with the same
result, all hang after printing the partition list of the hard drive.
I most recently tried Jen's 2.4 forward port, with about the same result,
though the following errors were printed before the kernel hung. (BTW,
Jen's a modified asm-sparc64/ide.h is below if you want to keep with your
2.4 port)
I am running in PIO mode, and saw that may be broken? And I realize that
there is probably not much interest/need for IDE to get working on this yet,
but I am wondering if you can point to some ideas to help me along with
figuring out what's going on. I am going to insert some printk's to see if
I can narrow down where I am hanging at, and if you have any thoughts on
where's the best place to look, I'd be most appreciative.
Thanks
Bruce H.
Patch below to get 2.4 forward port of IDE to compile on Sparc64...
