So, reducing the write buffer size to 8 bytes seem to be
first quick solution for the problem observed. The problem
didn't show up so far, but after approximately 1500 test
cycles another issue appeared: it is not possible to attach
the MTD device now. The kernel log is included below (note,
the hexdump of the trailing part of the PEB #39 containing
0xff is trimmed).

Kernel log ends here.

Additional limited dump of the PEB 39 (from offset 0 to 0xe0)
is included below since the EC header dump is not done in the
kernel log. We can see that the EC header's magic is ok, but
VID header's magic is zero.

My question is:
Is it possible that the reset occured while running in
nor_erase_prepare() just after clearing the VID header magic,
but before clearing the EC header magic?

If I clear the PEB 39 EC header's magic in U-Boot and then
boot Linux and try to attach the MTD device again, attaching
succeeds. Then, mounting the UBIFS partition succeeds, too.
