    SubjectHardlocks with 2.4.21-pre5, pdc202xx_new (PDC20269) and shared IRQs
    Hi,

    I am experiencing system hardlocks under the following conditions:
    - Hardware:
    - Tyan Thunder K7 w/ 2x Athlon MP 1.2GHz (5x PCI)
    - 2x Onboard Adaptec 7899P SCSI adapter
    IRQ 16, IRQ 17
    - 2x Onboard 3Com 3C982 100Mb 32bit PCI NIC
    IRQ 18, IRC 19
    - 1x National Semiconductor DP83820 1000Mb 64bit PCI NIC
    IRQ 16
    - 2x Promise Ultra 133TX2 PDC20269
    IRQ 16, IRQ 17
    - Software:
    - Linux 2.4.21-pre5:
    CONFIG_IDE=y
    CONFIG_BLK_DEV_IDEDISK=y
    CONFIG_BLK_DEV_IDEPCI=y
    CONFIG_BLK_DEV_GENERIC=y
    CONFIG_IDEPCI_SHARE_IRQ=y
    CONFIG_BLK_DEV_IDEDMA_PCI=y
    CONFIG_IDEDMA_PCI_AUTO=y
    CONFIG_BLK_DEV_IDEDMA=y
    CONFIG_BLK_DEV_ADMA=y
    CONFIG_BLK_DEV_PDC202XX_NEW=y
    CONFIG_IDEPCI_SHARE_IRQ=y
    CONFIG_IDEDMA_IVB=y
    CONFIG_BLK_DEV_PDC202XX=y
    CONFIG_BLK_DEV_IDE_MODES=y

    When one of the Promise controllers is sharing the same IRQ with one of
    the NICs (don't matter which, I tried all) and data is copied *to* the
    machine over the network, the system deadlocks. When data is copied
    *from* the system over the network, it works all ok. Unfortunately the
    system BIOS doesn't give me any possibility of setting the IRQ
    channels by hand, so all I can do is put the cards into other slots.

    Ah, at boot time the kernel spits out this message:
    --8<--
    I/O APIC: AMD Errata #22 may be present. In the event of instability try
    : booting with the "noapic" option.
    --8<--
    I've not yet tried that, but will do now.
