[rtl] 2.5 ms interrupt latency

[David Schleef <ds@stm.lbl.gov>]

I've been noticing some problems with really high *Linux* interrupt
latency in 2.2.9+beta5.  Actually, it seems like Linux is not
getting every interrupt from RTLinux.  This has caused things like
poor network performance, dropped TCP connections over PPP, and buffer
overruns on data acquisition cards.  Machine is a dual Pentium 150.
When I compile a stock 2.2.10 kernel, everything is fine.

If this has been noticed and/or fixed recently, let me know.
