I got an email from Boris Popov in regards to getting more silo
overflows after the SMP cleanup patch then before.
One thing the patch removed was the hack that allowed certain interrupts
(tty interrupts) to run in parallel with the supervisor.
Now, I must say, that there is no way we are going to add that hack back
in ... it was a real mess and is simply not worth it, and when we
move to the interrupt threading model we can truely make the serial
interrupt SMP-safe and do away with the issue once and for all.
I don't know if the mouse problems are related or not, did anyone have
jumpy-mouse problems before the SMP cleanup was committed? (i.e. in
kernels then two weeks old for 4.0, and four weeks old for 5.0).
