yes, snd-dt019x was loaded, but that make no difference. > could you try to put snd-usb-audio to /etc/hotplug/blacklist, so that > it's not automatically loaded. then we'll know the problem is related > only with snd-usb-midi. > in both cases: - without snd-usb-audio - without snd-usb-audio and without snd-dt019x the same occurs. Yes, good arguments for a problem in snd-usb-midi. Here is what I have done: just a modprobe and rmmod. ------------------- tuba:~# lsmod Module Size Used by Not tainted snd-mixer-oss 9056 0 (autoclean) (unused) snd 24136 0 (autoclean) [snd-mixer-oss] soundcore 3364 0 (autoclean) [snd] tuba:~# modprobe snd-usb-midi tuba:~# rmmod snd-usb-midi Segmentation fault tuba:~# lsmod Module Size Used by Not tainted snd-usb-midi 0 0 (deleted) snd-seq-virmidi 2728 0 [snd-usb-midi] snd-seq-midi-event 2872 0 [snd-usb-midi snd-seq-virmidi] snd-seq 37356 0 [snd-usb-midi snd-seq-virmidi snd-seq-midi-event] snd-timer 10400 0 [snd-seq] snd-rawmidi 12224 0 [snd-seq-virmidi] snd-seq-device 3856 0 [snd-usb-midi snd-seq snd-rawmidi] snd-mixer-oss 9056 0 (autoclean) (unused) snd 24136 0 (autoclean) [snd-usb-midi snd-seq-virmidi snd-seq-midi-event snd-seq snd-timer snd-rawmidi snd-seq-device snd-mixer-oss] soundcore 3364 0 (autoclean) [snd] tuba:~# -------------------- Jul 29 14:15:09 tuba kernel: usb.c: registered new driver snd-usb-midi Jul 29 14:15:09 tuba kernel: snd-usb-midi: using interface 1 Jul 29 14:15:09 tuba kernel: snd-usb-midi: MIDIStreaming version 01.00 Jul 29 14:15:09 tuba kernel: snd-usb-midi: using 1 input jack(s) on endpoint 1 Jul 29 14:15:09 tuba kernel: snd-usb-midi: using 1 output jack(s) on endpoint 2 Jul 29 14:15:09 tuba kernel: snd-usb-midi: detected Evolution Electronics L MK-2 49C USB MIDI keyboa Jul 29 14:15:14 tuba kernel: usb.c: deregistering driver snd-usb-midi Jul 29 14:15:14 tuba kernel: printing eip: Jul 29 14:15:14 tuba kernel: e2b20329 Jul 29 14:15:14 tuba kernel: Oops: 0002 Jul 29 14:15:14 tuba kernel: CPU: 0 Jul 29 14:15:14 tuba kernel: EIP: 0010:[<e2b20329>] Not tainted Jul 29 14:15:14 tuba kernel: EFLAGS: 00210246 Jul 29 14:15:14 tuba kernel: eax: 29323030 ebx: db5021c0 ecx: db502204 edx : db502100 Jul 29 14:15:14 tuba kernel: esi: db500c00 edi: 00001fff ebp: e2b3b7dc esp : db041ee4 Jul 29 14:15:14 tuba kernel: ds: 0018 es: 0018 ss: 0018 Jul 29 14:15:14 tuba kernel: Process rmmod (pid: 485, stackpage=db041000) Jul 29 14:15:14 tuba kernel: Stack: daf98380 dd446e00 e2b203ed db500c00 e2b18e5a daf98380 00001000 e2b18fc5 Jul 29 14:15:14 tuba kernel: dd446e00 db500c00 dd446e00 00000001 e2b3b7c0 e2b159ae dd446e00 00000001 Jul 29 14:15:14 tuba kernel: 00000000 e2b3aa01 dd446e00 dfe688d8 c021e47d dfe67800 dd446e00 dfe67300 Jul 29 14:15:14 tuba kernel: Call Trace: [<e2b203ed>] [<e2b18e5a>] [<e2b18fc5>] [<e2b3b7c0>] [<e2b159ae>] Jul 29 14:15:14 tuba kernel: [<e2b3aa01>] [usb_drivers_purge+141/224] [<e2b3b 7c0>] [usb_drivers_purge+62/224] [<e2b3b7c0>] [<e2b3b7c0>] Jul 29 14:15:14 tuba kernel: [usb_deregister+114/144] [<e2b3b7c0>] [<e2b3aa8a >] [<e2b3b7c0>] [free_module+23/160] [sys_delete_module+247/448] Jul 29 14:15:14 tuba kernel: [system_call+51/56] Jul 29 14:15:14 tuba kernel: Jul 29 14:15:14 tuba kernel: Code: 89 50 04 89 02 ff 4b 3c ff 43 44 0f 8e 05 07 00 00 53 56 e8 ------------------------------------------------------- This sf.net email is sponsored by: Dice - The leading online job board for high-tech professionals.
