Subject: Re: sja1000 interrupt problem

Hi all,
my tests at these targets:
- Core i7 / 5x PEAK cPCI with linux-3.10.25 (stable)
- Core i7 / 5x PEAK cPCI with linux-3.10.11-rt7 (rt)
- Core i7 / Dell 6510 Laptop linux-3.13.0-rc4 (mainline head)
are all successful so far (Intel i7 M640@2.80GHz).
There was no irq thread issue on the -rt kernel (for at least 4 hours under
heavy load) and my USB mouse worked every time when booting my Laptop (at
least 10 times).
I'll continue applying the patch on my machines to check for any issues. But
so far it looks great.
Best regards,
Oliver
