It looks like READ(10) commands don't work. I don't know the cause of the failures but it appears to be an old bug. Did you find any regression? I gather that your setup here is a QUANTUM LP240S target with Domex 3181 (DTC-436) card and g_NCR5380 module. I've been testing a similar setup: QUANTUM LPS540S target with a Domex 3191D (DTC-536) card and dmx3191d module. In both setups PIO is used exclusively, no IRQ is used, and FLAG_DTC3181E is set. I didn't see any issues in my tests, so your results are surprising. Let me know off-list if you want any help to debug this. Unfortunately, Domex Technology Corporation in Taiwan never responded to my requests for data on the DTC-536 device so there's probably no point in asking them for data on the DTC-436 device either. -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
