Hi! I am having this issue too. what should be noted: this is vanilla kernel, custom build, ARM architecture. adding eth0 to bridge is sometimes lethal and sometimes not. these messages were obtained from serial console.
doing "ip a" made the terminal stuck.. even though sshd listens, I can't connect to it anymore.. If I put more interfaces in the bridge, the bridge works as if nothing was wrong brctl addif br0 eth0 [ 224.792297] Unable to handle kernel NULL pointer dereference at virtual address 00000000 [ 224.800842] pgd = eef2c000 [ 224.803680] [00000000] *pgd=afaa9831, *pte=00000000, *ppte=00000000 [ 224.810424] Internal error: Oops: 80000007 [#1] SMP [ 224.815551] last sysfs file: /sys/devices/virtual/net/br0/bridge/forward_delay [ 224.823150] Modules linked in: bridge stp llc [ 224.827728] CPU: 0 Not tainted (2.6.39.1-omap4 #4) [ 224.833129] PC is at 0x0 [ 224.835876] LR is at br_change_mtu+0x60/0x78 [bridge] [ 224.841186] pc : [<00000000>] lr : [<bf00e268>] psr: 200f0013 [ 224.841186] sp : ef259e60 ip : eef9b808 fp : 00000000 [ 224.853271] r10: 00000001 r9 : ef258000 r8 : 00000000 [ 224.858764] r7 : eef9b900 r6 : c17a2540 r5 : c17a2000 r4 : 000005d4 [ 224.865631] r3 : 00000000 r2 : c17a2560 r1 : bf018985 r0 : c17a2994 [ 224.872467] Flags: nzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user [ 224.879974] Control: 10c5387d Table: aef2c04a DAC: 00000015 [ 224.886016] Process brctl (pid: 4285, stack limit = 0xef2582f8) [ 224.892242] Stack: (0xef259e60 to 0xef25a000) [ 224.896820] 9e60: c17a2000 c1515000 c17a2540 c0391174 c17a2000 bf00ff28 00000000 ef259ed8 [ 224.905426] 9e80: c17a2000 000089a2 00000000 00000000 00000000 c03936d0 000089a2 bea89bbc [ 224.914031] 9ea0: c0c07c40 c0393d00 00000000 00000001 0000006c 00000000 00000000 00000000 [ 224.922607] 9ec0: 00000000 00000002 00000000 ef67e314 ee8ae0a0 c00b08f0 00307262 00000000 [ 224.931213] 9ee0: 00000000 00000000 00000002 bea89d78 40108450 bea89e7a 00000000 00000000 [ 224.939819] 9f00: ef67e040 ef88a300 bea89bbc bea89bbc ef67e060 00000000 ef258000 00000000 [ 224.948425] 9f20: 00000000 c011fbb0 00000000 ef820620 ef258000 c0666488 00000004 c004bf08 [ 224.957000] 9f40: ef258000 00000000 00000000 c0129580 00000002 c1612300 00000000 ef958ee0 [ 224.965606] 9f60: 00000004 c004bf08 00000000 ef88a300 bea89bbc 000089a2 00000003 00000000 [ 224.974212] 9f80: ef258000 c011fc70 00000003 00000000 bea89e80 bea89e84 00000001 00000036 [ 224.982818] 9fa0: c004bf08 c004bd40 bea89e80 bea89e84 00000003 000089a2 bea89bbc bea89bbc [ 224.991424] 9fc0: bea89e80 bea89e84 00000001 00000036 bea89d78 00000000 40118000 00000000 [ 224.999999] 9fe0: 40271c30 bea89b94 0000b0c3 40271c3c 80000110 00000003 00000000 00000000 [ 225.008636] [<bf00e268>] (br_change_mtu+0x60/0x78 [bridge]) from [<c0391174>] (dev_set_mtu+0x40/0x78) [ 225.018371] [<c0391174>] (dev_set_mtu+0x40/0x78) from [<bf00ff28>] (br_add_if+0x300/0x3d8 [bridge]) [ 225.027893] [<bf00ff28>] (br_add_if+0x300/0x3d8 [bridge]) from [<c03936d0>] (dev_ifsioc+0x294/0x2b8) [ 225.037506] [<c03936d0>] (dev_ifsioc+0x294/0x2b8) from [<c0393d00>] (dev_ioctl+0x60c/0x704) [ 225.046295] [<c0393d00>] (dev_ioctl+0x60c/0x704) from [<c011fbb0>] (do_vfs_ioctl+0x4e0/0x554) [ 225.055267] [<c011fbb0>] (do_vfs_ioctl+0x4e0/0x554) from [<c011fc70>] (sys_ioctl+0x4c/0x6c) [ 225.064086] [<c011fc70>] (sys_ioctl+0x4c/0x6c) from [<c004bd40>] (ret_fast_syscall+0x0/0x3c) [ 225.072967] Code: bad PC value [ 225.077423] ---[ end trace 4bf8acca703efac4 ]--- Segmentation fault root@TPB:~# ls this is root's home's content -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
