Most importantly it panics or get witness warnings (lots of 'memory modified after free'). Panic goes like this (while kldunload if_bge with dhclient enabled): brgphy0: detached miibus0: detached bge0: firmware handshake timed out, found 0x4b657654 bge0: firmware handshake timed out, found 0x4b657654 bge0: detached bge0: <Broadcom BCM5705 A3, ASIC rev. 0x3003> mem ... bge0: firmware handshake timed out, found 0x4b657654 bge0: firmware handshake timed out, found 0x4b657654 miibus0: <MII bus> on bge0 brgphy0: <BCM5705 1/100/1000baseTX PHY> on miibus0 brgphy0: 10baseT, ... bge0: Ethernet address: ... bge0: firmware handshake timed out, found 0x4b657654 bge0: firmware handshake timed out, found 0x4b657654 bge0: discard frame w/o leading ethernet header (len 4294967192 pkt len 42949672) Kernel page fault with the following non-sleepable locks held: exclusive sleep mutex bge0 (network driver) r = 0 (0xffffffff80e81010) locked @ /usr/src/sys/modules/bge/../../dev/bge/if_bge.c:2828 ... As you can see the packet length is really bogus. I am wondering if the chip is actually initialized correctly to begin with. Jung-uk Kim
