System: NetBSD orchard.arlington.ma.us 1.3K NetBSD 1.3K (ORCHARDII) #22: Sun Mar 7 02:56:43 EST 1999 sommerfeld@orchard.arlington.ma.us:/usr/src/sys/arch/i386/compile/ORCHARDII i386
>Description:
kernel config messages are now so large (given new drivers and
chatty drivers (e.g., pciide, wscons, which prints ~50 characters per
virtual console) that they no longer fit in NBPG bytes on one
of my systems, which doesn't have an inordinate number of devices.
>How-To-Repeat:
boot system with wscons, a disk on pciide0, a few scsi disks,
raidframe, a couple devices on an aha, and the usual pc
stuff. (this doesn't seem like a very large system any more).
Watch msgbuf overflow.
>Fix:
Change the definition of MSGBUFSIZE in sys/arch/i386/include/param.h
to 2*NBPG from NBPG. I haven't tried this yet; sending a PR so this
doesn't get forgotten.
