====================================================================== ---------------------------------------------------------------------- Raymond - 05-22-06 14:57 ---------------------------------------------------------------------- The cause of the oops seem related to storing (void iomem *) to int Change "int port" to "unsigned long port" in snd_vortex_midi() MAY fix the oops without apply the patch in https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1833#8084 If it can't fix the oops, you will need to apply the the patch in https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1833#8084 Both Jon Masters's patch and Alan Horstmann's patch are already in HG repo Jon Master's patch is used to check whether io ports (0x330, 0x320, 0x310, 0x300 and the corresponding bit CTRL_MIDI_PORT is correct since au88x0 only ACK when combination is correct VORTEX_LEGACY_MIDI Alan Horstmann's patch is to prevent au88x0 enter into UART mode since mpu401 won't ACK to cmd RESSET if it is in UART mode ---------------------------------------------------------------------- Raymond - 05-22-06 16:49 ---------------------------------------------------------------------- The offset VORTEX_MIDI_DATA VORTEX_MIDI_CMD are different for au8820 and au8810/au8830 but VORTEX_MIDI_CMD = VORTEX_MIDI_DATA + 4 This mean struct snd_mpu401 *mpu in snd_vortex_midi() is also redudant alsa-kernel/driver/mpu401/mpu401_uart.c switch(hardware) { case MPU401_HW_AUREAL: mpu->cport = port + 4; break; case
