actually, it's now believed that this is a BIOS problem that affects all 
Linux versions. The aspect of v2.6.27 is that it happens to put kernel 
pagetables into the area that gets corrupted by the BIOS - and users 
notice that.

i.e. it's not a regression - unless i'm missing something.

|

so we either have to change the topic of this bug or better
close it and post new one nmi_watchdog related. I may do so
but since Joshua was opening bug it would be better if he
make such an action. How do you think? (I've asked Joshua
for additional info but it seems he is too busy now)

Yes, it should remain since it happened recently on 2.6.27-rc8-git6.
Again with blocksize = 1KB.

I don't see any action from the reiserfs developers about trying
to fix this.  Maybe I shouldn't bother testing this.


Here's the BUG dump from 2.6.27-rc8-git6:

When the file system is mounted, the module count is incremented. You
can't remove the module underneath a live file system.

2.6.28-rc1-git1: Reported regressions 2.6.26 -> 2.6.27

[Rafael J. Wysocki]

[Here's something new, a list of regressions introduced between 2.6.26 and
2.6.27.  We haven't fixed all of them yet and they're still being reported.
Also, they need to be fixed as well as those introduced later (although they
may be considered as "less important").

Quite frankly, I don't know how this is going to work out, but I thought
it's worth trying.  Enjoy! ;-)]

This message contains a list of some regressions introduced between 2.6.26 and
2.6.27, for which there are no fixes in the mainline I know of.  If any of them
have been fixed already, please let me know.

If you know of any other unresolved regressions introduced between 2.6.26
and 2.6.27, please let me know either and I'll add them to the list.
Also, please let me know if any of the entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

For details, please visit the bug entries and follow the links given in
references.

As you can see, there is a Bugzilla entry for each of the listed regressions.
There also is a Bugzilla entry used for tracking the regressions introduced
between 2.6.26 and 2.6.27, unresolved as well as resolved, at:

http://bugzilla.kernel.org/show_bug.cgi?id=11167

Please let me know if there are any Bugzilla entries that should be added to
the list in there.

Thanks,
Rafael

anyone to be interested in working on it.  It can be killed off.
I no longer care about it.
