This is OK. The whole goal of the write-buffer is to accumulate small
writes and to flush the whole page at once. It is assumed that the
minimal flash IO unit is c->wbuf_pagesize.

Could you please reproduce the problem, gather the log and send it
again, but with 2 notes:

1. please, output messages synchronously to a serial console (try dmesg
-n 8). When you use dmesg you see only the last output and loose
everything which does not fit the internal Linux output ring buffer.

2. AFAIU, after remount files disappear. Please, also send the log of
the second mount/
