With the LARTC 'wondershaper' HTB script [1] for good latency over ADSL, I get an oops [3] when sending traffic via ppp0 (and when bringing the interface down). Kernel is 2.6.0-test9 and 'debug 3333333' appended to the 'tc' command, to show HTB debug information [2] (not shown in [1]). Please CC me when replying, and I can provide further details, debugging, testing etc...this problem has been around for a while it seems. --- [1] (relevant lines from http://lartc.org/wondershaper/) tc qdisc add dev ppp0 root handle 1: htb default 20 tc class add dev ppp0 parent 1: classid 1:1 htb rate 210kbit burst 6k tc class add dev ppp0 parent 1:1 classid 1:10 htb rate 210kbit burst 6k prio 1 tc class add dev ppp0 parent 1:1 classid 1:20 htb rate 189kbit burst 6k prio 2 tc class add dev ppp0 parent 1:1 classid 1:30 htb rate 168kbit burst 6k prio 2 --- [2] (HTB debug messages) HTB init, kernel part version 3.13 htb_init sch=dc28e7f8 handle=10000 r2q=10 htb_dump sch=dc28e7f8, handle=10000 htb*g j=179519 lj=0 htb*r7 m=0 htb*r6 m=0 htb*r5 m=0 htb*r4 m=0 htb*r3 m=0 htb*r2 m=0 htb*r1 m=0 htb*r0 m=0 htb_get clid=10010 q=dc28e86c cl=00000000 ref=0 htb_get clid=10010 q=dc28e86c cl=00000000 ref=0 htb_get clid=10020 q=dc28e86c cl=00000000 ref=0 htb_get clid=10020 q=dc28e86c cl=00000000 ref=0 htb_get clid=10030 q=dc28e86c cl=00000000 ref=0 htb_get clid=10030 q=dc28e86c cl=00000000 ref=0 htb_tcf q=dc28e86c clid=0 fref=0 fl=00000000 htb_bind q=dc28e86c clid=10010 cl=00000000 fref=0 htb_tcf q=dc28e86c clid=0 fref=1 fl=df4ecd7c htb_bind q=dc28e86c clid=10010 cl=00000000 fref=1 htb_tcf q=dc28e86c clid=0 fref=2 fl=df4ecd7c htb_bind q=dc28e86c clid=10010 cl=00000000 fref=2 htb_tcf q=dc28e86c clid=0 fref=3 fl=df4ecd7c htb_bind q=dc28e86c clid=10020 cl=00000000 fref=3 htb_reset sch=dc28e7f8, handle=10000 --- [3] (ksymoops-processed oops report) Oops: 0000 [#1] CPU: 0 EIP: 0060:[<c02cbbad>] Not tainted >>EIP; c02cbbad <htb_enqueue+ab/126> <===== >>ebx; ffffffff <__kernel_rt_sigreturn+1bbf/????> >>ecx; dc28e86c <_end+1be20f60/3fb906f4> >>esi; d9cf3f50 <_end+19886644/3fb906f4> >>edi; dc28e7f8 <_end+1be20eec/3fb906f4> >>ebp; dbef5ab8 <_end+1ba881ac/3fb906f4> >>esp; dbef5a9c <_end+1ba88190/3fb906f4> Trace; c02b3570 <dev_queue_xmit+593/73a> Trace; c02e9c98 <ip_finish_output2+0/1c4> Trace; c02e9d97 <ip_finish_output2+ff/1c4> Trace; c02c0259 <nf_hook_slow+ef/13a> Trace; c02e9c98 <ip_finish_output2+0/1c4> Trace; c02e76d7 <ip_finish_output+21d/222> Trace; c02e9c98 <ip_finish_output2+0/1c4> Trace; c02bff12 <nf_iterate+6b/9f> Trace; c02e9c80 <dst_output+15/2d> Trace; c02c0259 <nf_hook_slow+ef/13a> Trace; c02e9c6b <dst_output+0/2d> Trace; c02e9620 <ip_push_pending_frames+3ac/408> Trace; c02e9c6b <dst_output+0/2d> Trace; c030da69 <udp_push_pending_frames+134/23c> Trace; c030e1b4 <udp_sendmsg+60d/f3d> Trace; c031900a <inet_sendmsg+4b/56> Trace; c02aa4cc <sock_sendmsg+92/af> Trace; c02aa582 <sock_recvmsg+99/b4> Trace; c02a9f68 <move_addr_to_kernel+7e/a7> Trace; c02b01a0 <verify_iovec+80/fa> Trace; c02ac13d <sys_sendmsg+256/2f4> Trace; c0141e28 <filemap_nopage+21c/2f9> Trace; c0155610 <do_no_page+29b/631> Trace; c0155c54 <handle_mm_fault+132/30c> Trace; c018becd <inode_update_time+8e/b9> Trace; c0119419 <do_page_fault+34b/56a> Trace; c02ac67e <sys_socketcall+261/29a> Trace; c0164327 <sys_write+5b/5d> Trace; c010a3eb <syscall_call+7/b> Code; c02cbbad <htb_enqueue+ab/126> 00000000 <_EIP>: Code; c02cbbad <htb_enqueue+ab/126> <===== 0: 8b 43 04 mov 0x4(%ebx),%eax <===== Code; c02cbbb0 <htb_enqueue+ae/126> 3: 89 44 24 04 mov %eax,0x4(%esp,1) Code; c02cbbb4 <htb_enqueue+b2/126> 7: c7 04 24 2b 30 38 c0 movl $0xc038302b,(%esp,1) Code; c02cbbbb <htb_enqueue+b9/126> e: e8 e3 6e e5 ff call ffe56ef6 <_EIP+0xffe56ef6> Code; c02cbbc0 <htb_enqueue+be/126> 13: 31 00 xor %eax,(%eax) <0>Kernel panic: Fatal exception in interrupt -- Daniel J Blueman NEU FÜR ALLE - GMX MediaCenter - für Fotos, Musik, Dateien...
