Since MSI support on some motherboards is unreliable, change the default interrupt mode from MSI to MSI-X. This patch avoids that the following message appears sporadially in the kernel logs of my test setup: do_IRQ: 3.193 No irq handler for vector Signed-off-by: Bart Van Assche <bart.vanassche@wdc.com> Cc: Christoph Hellwig <hch@lst.de> Cc: Hannes Reinecke <hare@suse.de> Cc: Johannes Thumshirn <jthumshirn@suse.de> --- drivers/block/skd_main.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
