Upon reboot after installing new kernel, booting into single user mode, installing world, and running mergemaster, dc0 starting reporting "dc0: TX underrun -- resetting" and "dc0: watchdog timeout" messages, and no traffic was getting through the NIC. I reverted sys/pci/if_dc.c and sys/pci/if_dcreg.h to the previous versions, (1.9.2.5 and 1.4.2.3 respectively), rebuilt the kernel, and rebooted. With the previous versions of these files, the NIC functions normally. >How-To-Repeat: >Fix: Temporary fix is to back out sys/pci/if_dc.c version 1.9.2.6 and sys/pci/if_dcreg.h 1.4.2.4. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
