It used to happen in the middle of our IO test application, now it happened much early in our test spinup process with debugging version of ata_host_intr() function. We boot up the target (ARM XScale processor) with hard drive powered off, then power up the drive and do test spinup. What test spinup does is to issue sysfs user scan on the port followed by Identify Device. Below is my debugging version of ata_host_intr() function with ATA_IRQ_TRAP enabled and hacked. What puzzled me is that none of the sub-counters (initial value is 1) get incremented in most failures? Please see dmesg log for details. I did see one failure (out of many) where "idle_irq_hsm_state" is incremented and matches "idle_irq" counter though.

* Re: Change Libata Error Handling for Drive Testing 2007-03-20 5:14 ` Fajun Chen @ 2007-03-22 16:49 ` Fajun Chen 0 siblings, 0 replies; 5+ messages in thread From: Fajun Chen @ 2007-03-22 16:49 UTC (permalink / raw) To: Tejun Heo; +Cc: linux-ide@vger.kernel.org Hi Tejun, JFYI, it turns out that spurious interrupts was caused by User Scan before drive is ready. I wait for 2 seconds after drive is powered on which is not sufficient for some drives. Alt status should be checked first but there's no good way to check it in user space. Does User Scan related code check alt status before drive is touched?
