SubjectWhich came first, hard kernel lockup or SATA errors?
Date
I'm trying to untangle a series of problems that suddenly occurred on
a dual-socket Xeon server system that had been running a bunch of KVM
workloads just fine for over 6 weeks (4.4.52-grsec kernel,
Debian-derived userspace).

Here are the highlights, with timestamps in seconds:

...and so on for 2 more hours, until the system was finally rebooted

First I want to know if I can blame the whole mess on flaky
hardware. The error messages marked with ** are from IO operations on
two SATA SSDs. On one hand, getting errors from two different drives
at the exact same time suggests that the drives themselves aren't the
problem. On the other hand, the fact that the system has two other
drives connected to the same controller that continued to work (even
though all were being accessed more or less simultaneously in a
software RAID-10 configuration) suggests that the controller isn't
totally broken. (The controller is embedded in the C610 PCH on the
motherboard.) No SATA errors have occurred on that system before or
since.

Is there any chance that those SATA errors could have been caused by
the kernel lockups--say due to a timing-sensitive interrupt not
getting serviced? Or by any other conceivable software problem?

If not, is it plausible that a hardware problem with the SATA
controller or drives caused the kernel lockups, even though the first
hard lockups were reported 48 seconds before the first SATA error
messages?

Following is an excerpt of the console log. Let me know if any other
details would be helpful.
