Here are 4 patches against the 'master' branch of the Jens Axboe's 'linux-blobk.git' repo plus the 'pataep_93xx' driver patch re-posted yesterday. The affected drivers use platform_get_irq() which may return IRQ0 (considered invalid, according to Linus) that means polling when passed to ata_host_activate() called at the end of the probe methods. I think that the solution to this issue is to explicitly deny IRQ0 returned by platform_get_irq()... [1/4] pata_bk3710: deny IRQ0 [2/4] pata_ep93xx: deny IRQ0 [3/4] pata_ftide010: deny IRQ0 [4/4] pata_imx: deny IRQ0
