Attaching failed suspend-resume log. Comments: 1) Unrecoverable read error reported, but device is fully readable when tested manually few seconds later. Device probably needs more time to settle, maybe analog of rootdelay= is required for resume? 2) Corruption exists also when no resume procedure executed (by manually ejecting device or system hard reset). 3) Kernel suspected to mess with VFS/USB suspending orders or by not providing enough time for USB device to commit data physically before suspend/reseting/turning-off USB host, after sync. 4) Several USB storage devices were tested, they all fail.
