From: wforms@Safe-mail.net To: bug-followup@freebsd.org Cc: marius@alchemy.franken.de, "Andy Farkas" Subject: Re: kern/112654: [pcn] Kernel panic upon if_pcn module load on a Netfinity 5000 Date: Tue, 22 Jan 2008 19:23:17 +0100 New test was carried out today using Marius' patch (and not using Andy's patch at the same time). The new kernel re-introduces the original problem, loading the if_pcn driver while the RJ45 cable is connected results in a kernel panic and the system reboots. While the cable is disconnected the if_pcn module loads fine, after which the cable can be plugged back and the card can be used as expected. ### Here is what shows up upon "kldload if_pcn" while the cable is unplugged ### pcn0: port 0x2180-0x219f mem 0xfebff800-0xfebff81f irq 17 at device 9.0 on pci0 pcn0: Chip ID 2624 (Am79C972) miibus5: on pcn0 nsphyter0: on miibus5 nsphyter0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto ukphy0: on miibus5 ukphy0: 10baseT, 10baseT-FDX, auto pcn0: Ethernet address: 00:06:29:50:d9:9e ### At that point ifconfig says: ### root@netfinity ~# ifconfig pcn0 pcn0: flags=8802 mtu 1500 ether 00:06:29:50:d9:9e media: Ethernet autoselect (none) status: no carrier ### Then I connect the RJ45 cable coming from the switch and: ### root@netfinity ~# ifconfig pcn0 pcn0: flags=8802 mtu 1500 ether 00:06:29:50:d9:9e media: Ethernet autoselect (100baseTX ) status: active root@netfinity ~# ### Now here is what "kldload if_pcn" does while the cable is connected: ### pcn0: port 0x2180-0x219f mem 0xfebff800-0xfebff81f irq 17 at device 9.0 on pci0 pcn0: Chip ID 2624 (Am79C972) miibus5: on pcn0 nsphyter0: on miibus5 nsphyter0: no media present ifmedia_set: no match for 0x0/0xfffffff panic: ifmedia_set Regards, Keve
