Here is a revisited version of Heikki's patch applicable against an
Adeos-patched kernel, and which is expected to solve the lagging
interrupt sync
issue; tested on a mpc8541 board. I'd be interested to know if this
still fixes
the issue discovered on ppc64, and maybe on the G4.
Does not change a thing on the G4.
Of, so if Heikki confirms that this patch works on ppc64, I guess that
we have a
brand new shiny bug to chase, with lots of headbanging sessions ahead.
And I'm
not talking about dance style here...
I've now tried both 32- and 64-bit kernels on the G5 with and without
the patch and the results seem consistent with the G4. Without the
patch, stalls happen always with nucleus loaded, but I didn't observe
any with the patch. However, I'm still not happy with how the patch
handles the !threaded case: If everyone had handlers like
my_handler(...);
{
traps++;
return PROPAGATE;
}
the patch wouldn't help at all. I'd prefer something more along the
lines of my original posting.
