    With DEBUG_SLAB on, I can run only a very short time under 2.6.23
    before a kernel panic.

    [ 626.028180] eth0: too many iterations (6) in nv_nic_irq.
    [ 626.167583] eth0: too many iterations (6) in nv_nic_irq.
    [ 626.206729] eth0: too many iterations (6) in nv_nic_irq.
    [ 626.400171] eth0: too many iterations (6) in nv_nic_irq.
    [ 626.446374] eth0: too many iterations (6) in nv_nic_irq.
