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. # uname -a FreeBSD celebris 5.0-CURRENT FreeBSD 5.0-CURRENT #0: Sat Jul 1 \ 13:20:10 PDT 2000 tomdean@celebris:/usr/src/sys/compile/CELEBRIS-SMP \ 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. tomdean === console messages ===== Jul 3 20:04:11 celebris /kernel: de0: abnormal interrupt: transmit underflow Jul 3 20:04:11 celebris /kernel: de0: abnormal interrupt: transmit underflow Jul 3 20:04:43 celebris /kernel: de0: abnormal interrupt: transmit underflow Jul 3 20:04:43 celebris /kernel: de0: abnormal interrupt: transmit underflow ==== dmesg ================ Copyright (c) 1992-2000 The FreeBSD Project.
