Hi,
I went from 2.6.19+sata_nv-adma-ncq-v7.patch, with no problems and adama
enabled, to 2.6.20-rc5, which gave me problems almost instantly.
I just thought that it might be interesting to know that it DID work
nicely.

Well that's interesting.. The only significant change that went into
2.6.20-rc5 in that driver that wasn't in that version you mentioned was
this one:
http://www2.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2dec7555e6bf2772749113ea0ad454fcdb8cf861
Could you (or anyone else) test what happens if you take the 2.6.20-rc5
version of sata_nv.c and try it on 2.6.19? That would tell us whether
it's this change or whether it's something else (i.e. in libata core).
Assuming that still doesn't work, can you then try removing these lines
from nv_host_intr in 2.6.20-rc5 sata_nv.c and see what that does?
/* bail out if not our interrupt */
if (!(irq_stat & NV_INT_DEV))
return 0;
as that's the difference I'm most suspicious of causing the problem.
