Hi, I was installing 6.0-BETA3 on an Nvidia nForce2 motherboard from FTP with the onboard nve adapter and got the following panic: panic: nve_ifstart: attempted use of a free mbuf! cpuid= 0 KDB: enter: panic [thread pid 35 tid 100017 ] Stopped at kdb_enter+0x2b: nop db> trace Tracing pid 35 tid 100017 td 0xc1d4a900 kdb_enter(c08574d4) at kdb_enter+0x2b panic(c082aefa,c081567c,c1eb250c,354,d8790740) at panic+0x127 nve_ifstart(c1eb2400) at nve_ifstart+0x35a if_start(c1eb2400) at if_start+0x7b ether_output_frame(c1eb2400,c1fe8e00,0,0,0) at ether_output_frame+0x1d9 ether_output(c1eb2400,c1fe8e00,c203d070,c2077bdc,c2066a00) at ether_output+0x3b4 ip_output(c1fe8e00,0,d3628ae0,0,0) at ip_output+0x6fc tcp_ouput(c20e1ac8) at tcp_output+0xfb2 tcp_input(c1eb7b00,14,c1eb7b00,0,0) at tcp_input+0x13cc ip_input(c1eb7b00) at ip_input+0x511 netisr_processqueue(c096ffd8) at netisr_processqueue+0x6e swi_net(0) at swi_net+0xbe ithread_loop(c1d94580,d3628d38,c1d94580,c061f924,0) at ithread_loop +0x11c fork_exit(c061f924,c1d94580,d3628d38) at fork_exit+0xa0 fork_trampoline() at fork_trampoline+0x8 --- trap 0x1, eip = 0, esp = 0xd3628d6c, ebp = 0 --- db> I transcribed the backtrace by hand so please forgive any typos. I can reproduce this if there is any more information needed. Unfortunately as it's a fresh install I can't get a dump. The nve interface is: nve0: <NVIDIA nForce MCP2 Networking Adapter> port 0xd400-0xd407 mem 0xe0005000-0xe0005ffff ird 20 at device 4.0 on pci0 nve0: Ethernet address 00:00:00:40:06:01 miibus0: <MII bus> on nve0 ukphy0: <Generic IEEE 802.3u media interface> on miibus0 ukphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto nve0: Ethernet address: 00:00:00:40:06:01 nve0: [GIANT-LOCKED] Cheers Phil Murray
