NetBSD 4.0_BETA2 (INSTALL_LARGE) #0: Sun May 20 22:07:43 PDT 2007

>Description:
I have lots of old ISP2150G servers (Intel dual PIII-class server platform), all with extra mylex (Acceleraid 250) and additional gigabit card. During boot of INSTALL_LARGE image (via PXE) I notice many lines about 'lost interrupts' from various devices. 

AFAIR older versions (like NetBSD 3.x) hasn't any problems. Linux kernel works perfectly, so it is - probably - not a hardware problem.

Kernel taken from 200705200002Z netbsd-4 snapshot.

Session (captured via serial console), below:
