Subject: Re: UBIFS oops after remount ro
Date: Mon, 29 Nov 2010 14:18:07 +0100 [thread overview]
Message-ID: <20101129131807.GB23237@leila.ping.de> (raw)
In-Reply-To: <1290785057.2552.14.camel@localhost>
Hi Artem,
I can now reproduce the Oops with CONFIG_UBIFS_FS_DEBUG and your
patch. However, I had to manually apply the hunks because my tree
seems to differ enough for patch to not apply it automatically...
My observations so far:
- I have to re-flash the whole UBI image, simply removing the
directory that is created with the script is not sufficient
to trigger the Oops on subsequent re-start.
My guess is that not only the single remount r/w->r/o cycle
from the first script is needed but the complete sequence of
2 r/w->modify->r/o "cycles" currently in my startup scripts.
Hopefully it's not really depending on filesystem internal state...
- I have to power cycle the board after flashing.
(I flash from an NFS-root system) Simply issuing a reboot from
the NFS-root system does result in a clean restart. When stopping
the boot progress in the U-Boot prompt and issuing 'reset' from
there sometimes also triggers the Oops on the following re-start
with the newly flashed image, but doing a power cycle gave a 100%
chance to get the oops in my tests.
The inode in question is always the same, but I guess this is not
a surprise as I always start with the same UBI Image?
I have to think about this a bit, still having no clue what is
going on and not too much a clue about what I am looking for either,
so sorry for just posting this weird information...
Regards,
Wolfgang
