System: NetBSD pattern 1.0A NetBSD 1.0A (PATTERN) #41: Mon Jul 24 22:26:13 EDT 1995     jtk@pattern:/u1/NetBSD-current/src/sys/arch/i386/compile/PATTERN i386

>Description:
When running disk-intensive operations with both a DC21041 and a ppp
line (ISDN 56000 bps, 57600 serial line rate), I got frequent panics.
One was a "malloc: wrong bucket".

>How-To-Repeat:
beat on ppp and another net at the same time

>Fix:
This sesm to have cured my problems, but I can't be sure I'm just being
lucky after rebooting.
