While I don't think Doug has MSI-X adapters, a complete patch would

all request_irq() calls to use IRQF_DISABLED, right?
The above patch takes care of replacing all the IRQF_SHARED flags
in irq
registrations with IRQF_DISABLED.
Yes ... but even for the MSI-X case, you want the handler to be run
with
interrupts disabled, don't you? If not, why not?
Yeah you're right. For some reason, request_irq for MSI-X passes 0 as
the irq flag. We need to take care of that.
Thanks,
