c/s 18726 ???

[Jan Beulich]

This one basically disables MSI with a pretty vague comment - is there any
more detail on where the issues are here? I'm asking because I had to
undo this in order to make sure the NR_IRQS patches really work as
expected...

Thanks, Jan

This is because currently the pci_enable_msi will be called with irq disabled, this will trigger check_lock() failed on debug version.
I try to get a patch for it but still not finished :(

Thanks

The locking's screwed so debug builds crash in check_lock(). Yunhong is
working on a fix.
