After upgrading my kernel to 4.19 I got a corruption on nearly every reboot or resume from suspend on my Acer s7-391 [UEFI boot].
Going to my UEFI setup and changing IDE mode from IDE to ATA seems to have resolved the issue for me. Don't know, though, if that is a valid data point or if it was a mere accident (tested only on one computer) or just avoids the Bad Timing by a few nanoseconds....
