Well, it's worse than this. After 7 or 8 bisections (all flagged
bad) the symptoms changed: the system boots up to the point where
it does not recognize LVM volumes. So there are at least 3 bugs:
1) the timeout on interrupts (only seen on hdb)
2) the empty DMA table messages (seen on hda and hdb)
3) the inability to see logical volumes ("pvs" does not find them,
they are back when rebooting into 2.6.24). This is the apparently
the earliest introduced bug (no problems with the disks with that
version).
I am away from that machine until next Tuesday. IIRC the last git
bisect was something like 160 revisions left.

Heh :-) Recent powermacs are trivial to open ! But yeah, I do need to produce a driver for libata one of these days. On my todo list ...

Neither of these things exist at the moment so lets stick to the existing
code which is scheduled for 2.6.26 and which finally allows removal of ppc
specific ide hacks from arch/{powerpc,ppc} (500 LOC gone, patches to be
posted this week), not to mention other nice changes in the future...
Thanks,

Also, the above would have the advantage of not relying on drivers/ide infrastructure, and thus working with libata (once somebody has ported pmac ide to libata).

Pegasos doesn't use the pmac ide which is what we were discussing. It uses a VIA IDE which uses a normal PRD table. So something else must have broken...

Argh, the first bisect point ended up with timeouts on hdb... Flagged as bad, to try to see when the problems started, but I suspect that there are several.

Well, I have serious problem on a Pegasos which appeared some time between 2.6.24 and 2.6.25-rc1: at boot I get an infinite string of hdb: empty DMA table? I'm trying to bisect it right now.
