Hi all, I am having a strange problem when trying to ping a UML guest from the host, right after I have the guest eth0 come up (both Debian). Basically, I am doing: guset#: ifconfig etho <guest-ip> up and then host#: ping <guest-ip> and the guest UML then immediately bombs out with a segmentation fault. (I am using 2.6.10-skas3-v8-rc2 on the host, and 2.4.26-3um on the guest). The /var/log/messages file shows the following output: ===================================== output start ============== Feb 19 19:23:09 millis kernel: <6>skput:over: cf80234e:42 put:42 dev:<NULL>------------[ cut here ]------------ Feb 19 19:23:09 millis kernel: Modules linked in: tun usbkbd usbcore Feb 19 19:23:09 millis kernel: CPU: 0 Feb 19 19:23:09 millis kernel: EIP: 0060:[skb_over_panic+59/80] Not tainted VLI Feb 19 19:23:09 millis kernel: EFLAGS: 00010292 (2.6.10-skas3-v8-rc2) Feb 19 19:23:09 millis kernel: EIP is at skb_over_panic+0x3b/0x50 Feb 19 19:23:09 millis kernel: eax: 0000002c ebx: ce341720 ecx: c03ad54c edx: c03ad54c Feb 19 19:23:09 millis kernel: esi: cbbfba82 edi: 0000002a ebp: c742c220 esp: c6467f14 Feb 19 19:23:09 millis kernel: ds: 007b es: 007b ss: 0068 Feb 19 19:23:09 millis kernel: Process linux (pid: 2682, threadinfo=c6466000 task=cb098600) Feb 19 19:23:09 millis kernel: Stack: c0392280 cf80234e 0000002a 0000002a c036d43c cf80235a ce341720 0000002a Feb 19 19:23:09 millis kernel: cf80234e 0000002a 00080000 cf802380 c64457e0 c6467fac 0000002a cf8023b7 Feb 19 19:23:09 millis kernel: c64457e0 c6467f64 00000001 c6467fac a69ebc62 0000002a c0149228 c64457e0 Feb 19 19:23:09 millis kernel: Call Trace: Feb 19 19:23:09 millis kernel: [pg0+255210318/1068889088] tun_chr_writev+0x15e/0x190 [tun] Feb 19 19:23:09 millis kernel: [pg0+255210330/1068889088] tun_chr_writev+0x16a/0x190 [tun] Feb 19 19:23:09 millis kernel: [pg0+255210318/1068889088] tun_chr_writev+0x15e/0x190 [tun] Feb 19 19:23:09 millis kernel: [pg0+255210368/1068889088] tun_chr_write +0x0/0x40 [tun] Feb 19 19:23:09 millis kernel: [pg0+255210423/1068889088] tun_chr_write +0x37/0x40 [tun] Feb 19 19:23:09 millis kernel: [vfs_write+184/304] vfs_write+0xb8/0x130 Feb 19 19:23:09 millis kernel: [sys_write+81/128] sys_write+0x51/0x80 Feb 19 19:23:09 millis kernel: [syscall_call+7/11] syscall_call+0x7/0xb Feb 19 19:23:09 millis kernel: Code: c0 0f 44 c2 89 44 24 10 8b 44 24 1c 89 44 24 0c 8b 41 60 c7 04 24 80 22 39 c0 89 44 24 08 8b 44 24 20 89 44 24 04 e8 e5 d0 e3 ff <0f> 0b 5b 00 82 fa 38 c0 83 c4 14 c3 89 f6 8d bc 27 00 00 00 00 ===================================== output end ============== Does anyone have any ideas what is causing this and what the output means and how I coudl go about fixing it? I built the host kernal from 2.6.10, with the skas3 patch and guest is what the Debian package brings over from unstable. I've not found any pointers to what it could be so far.
