We are working on this and we will have an update for this. I tested todays 5.0.0-rc5-00358-gdf3865f on my sparcs and a couple of servers that have qla2xxx FC adapter gave me this warning:[ 19.746300] qla2xxx [0000:00:00.0]-0005: : QLogic Fibre Channel HBA Driver: 10.00.00.12-k.[ 19.746599] qla2xxx [0000:02:00.0]-001d: : Found an ISP2432 irq 18 iobase 0x(____ptrval____).

Today I tried another sparc with newer OS and gcc and older hardware platform (Sun V445) and that did not exhibit the problem with QLA2422. PCI-MSI is still present there too but does not seem to be used for qla2xxx (it has "sun4v -IVEC" irq type).
