ok, thanks.

But the unstable bit problem is different from software timeout
related issues regarding UBI and NOR flash the OP mentioned.
It is anyway good to hear work is in progress here.

I asked about the software timeout issue because I've seen false
timeouts with powerpc + CONFIG_NO_HZ a while ago.
In my case the low-level do_write_buffer (cfi_cmdset_0002.c) timed
out too early. See
