> I'm super puzzled right now :-( > There are three strawman` ideas out of head, down by a level of naiveness increase: - disk controller corrupts DMA chunks themselves, could be tested against usb stick/sd card with same fs or by switching disk controller to a legacy mode if possible, but cascading failure shown previously should be rather unusual for this, - SMP could be partially broken in such manner that it would cause overlapped accesses under certain conditions, may be checked with 'nosmp', - disk accesses and corresponding power spikes are causing partial undervoltage condition somewhere where bits are relatively freely flipping on paths without parity checking, though this could be addressed only to an onboard power distributor, not to power source itself. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
