I have been seeing unusual error messages in response to network
transmissions. The latest was caused by lp ~0.5MB to a remote
printer.
I am running -current SMP. Dmesg is attached. The error messages are
attached.

i386
These messages started April 26, I believe.
I did cvsup, make world, and kernel on Apr 4, May 28, June 21, and,
Jul 1.
The printer is an HP Laserjet, on a FreeBSD 3.4-stable of Apr 17,
2000, 486DX2/66 machine connected via 10base2/BNC net. The '486
machine is only for the printer, ppp, and serves a 3G disk for 0330
daily backup from a remote machine. The printer has very light use.
I don't see any of the interrupts in response to the backup activity.
