    Kernel 2.2.15-pre9 locks solid on a MediaGX based box with the message:
        Too much work in interrupt on uart401 (0x330): UART jabbering??
    when the midi device (/dev/sequencer) is accessed. It also complains
    once (harmlessly it seems) on boot. When the device is accessed,
    the kernel is history.

    I'm working with a few boxes using Cyrix MediaGX cpu's and
    the Cyrix CX5530 chipset. I'm compiling the kernel using
        CONFIG_SOUND_SB=y
        CONFIG_SB_BASE=220
        CONFIG_SB_IRQ=7
        CONFIG_SB_DMA=1
        CONFIG_SB_DMA2=5
        CONFIG_SB_MPU_BASE=330
        CONFIG_SB_MPU_IRQ=5
    to use the builtin sound blaster emulation. These settings match
    those of the MPU401 device (set via the BIOS).

    Has anyone made the MPU401 work with a MediaGX?
    Have I missed something obvious?
