This is a compile flag put into the kernel expressly to deal with a disk
corruption issue the occurs after suspend-resume for IBM Thinkpads
because of the BIOS.  You have to set it, and recompile the kernel.

Some distributions may already provide a kernel that has this option
configured.  I don't know.

I can't explain about the errors you're receiving - the fact it had to
do with suspend-resume caught my eye.  It was the only thing I knew that
was related, and no one else had provided any suggestions to try.

Even if it's not the source of the issues you're asking about, it's
still something to deal with if you have a Thinkpad.  And if it turns
out to fix it, bonus.

I can't help you with this, but I'd think if you're going to go to that
much trouble, apply the effort to discovering and fixing the problem in
the first place...
