This might as well be another stack overflow.  You don't happen to have
more lines of the stack trace?  I fear this might be another case of
direct reclaim hitting you.

Try backporting commit 070ecdca54dde9577d2697088e74e45568f48efb
"xfs: skip writeback from reclaim context", that should get rid of
places calling into ->writepage with already deep stack usage.
