Hello
Can we have some version number after kernel version for fixups as
latest upload for .36 on kernel.org is from 27-Dec-2010 21:17
That's the 3rd version for .36 with same name, so there'll probably be
some confusion :D
Ok, I'll put additional ones suffixed with "-x" (x=1, 2, ...)
Edward.
Thanks

Hello.
Could you please try the attached patch?
This patch is against reiser4-for-2.6.36.
Also please make sure you have the latest one
(I have updated the stuff 11-Dec-2010).
Report, if any problems.
Thanks,
Edward.

Wanted to try reiser4. I have compiled a kernel with reiser4, format
the partition and began to copy the folder /home.
After a short time the screen goes black and there was one console
with the error output. After switching to other tty and back up
continued. dmesg output copied to the pastebin
(http://pastebin.com/XyDKWJ8J).
This was repeated several times and the computer hangs perfectly still.
I have ubuntu 10.10 on a laptop Acer Aspire 7720z.
Yup, I see the bug:
instead of writing pages reiser4 kicks ext4 to do it,
and, I guess, doesn't clear journal_info (this is why
ext4 oopses).

It is interesting that the path
entd -> writeback_inodes_wb -> ext4_da_writepages
has never been triggered on my testing machine (I also
have reiser4 and ext4 there). Perhaps, this is because
of different system configurations.
I'll try to fix it in the near future, so that you'll be able to
try reiser4.
Thanks for your report,
Edward.
