Hallo,

we use a mini PCIe card (9390) with a miniPCe to PCIe adapter on a X86 
system and a system with a Xilinix Microblaze CPU.
As the performance on the Microblaze is bad (ping times up to 10 sec), 
we examined the interrupt service routine.

On Microblaze *and* on X86 we see about 10 "spurious" interrupts per 
second.
In this cases in ar9003_hw_get_isr (ar9003_mac.c) the sync_cause bit 
"AR_INTR_SYNC_HOST1_PERR" is set.
The driver ignores this.

Does AR_INTR_SYNC_HOST1_PER indicate a PICe parity error ?

We use Kernel 3.1.4.
