Blair,
I should clarify that I am *now* aware of your support case =D
For anyone willing to run a systemtap the following should give us more
information about the problem.
stap --all-modules -e 'probe kernel.function("handle_bad_sector"){ printf("handle_bad_sector(): ARGS is %s\n",$$parms$$); print_backtrace()}'
In order to run this you will need to install some non-trivial packages such as
the kernel debuginfo package and kernel-devel. This is generally best
accomplished as follows, at least on rpm based systems.
(yum|dnf) install systemtap
stap-prep
The systemtap needs to be running when the error is generated as it monitors
calls to "handle_bad_sector" which is the function generating the error message.
Once that function is called the probe will dump all information about the bio
structure passed as a parameter to "handle_bad_sector" as well as dumping the
call stack. This would give us a good idea of the specific code involved.
