The following are pure speculations, I'd rather let David speak, but just in case; on 16/08/2011 18:45 John Baldwin said the following: > Well, that would seem odd, still.

Maybe it doesn't do that exactly because device and vendor ID are zeroes as David described earlier. [David S.] The vendor and device IDs are NOT zeros. They are valid numbers. The SubSystem Vendor and Device IDs are zeros. > Also, the ATA driver only allocates its BAR once, so it shouldn't > trigger the panic in question in that case (the panic is only triggered when > you > try to double-allocate a BAR). This makes only if the BAR has sane values. Not sure what happens if the BAR has some junk that duplicates other PCI device, or something like that. -- Andriy Gapon This message and any attached documents contain information from QLogic Corporation or its wholly-owned subsidiaries that may be confidential.
