Returning ED_HPP_IO_PORTS (the number of I/O ports occupied by the device) appears to be behavior from the v3 driver that was missed in building the v4 driver. >How-To-Repeat: Install/configure HP PCLAN+ card; boot 4.1-RELEASE install media; configure ed0 device appropriately; observe that ed0 is not detected. Compare with 3.4-RELEASE behavior. >Fix: Change the last line of ed_probe_HP_pclanp() to return zero. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
