System: NetBSD himo.salmi.ch 2.0G NetBSD 2.0G (GENERIC) #0: Thu Aug 12 23:26:18 CEST 2004 build@himo.salmi.ch:/build/nbsd/usr/src/sys/arch/i386/compile/GENERIC i386
Architecture: i386
Machine: i386
>Description:
On a -current NetBSD i386 system I'm having problems writing to a
USB CF adapter. When running a GENERIC kernel built using sources
from three days ago, writing to the CF almost always causes the writing
process to hang (ps state D) until I disconnect the device (which
sometimes crashes the kernel). When running a GENERIC kernel with
ehci disabled, writing to the CF succeeds without any problem.

Partial dmesg output from the system in question:
