Kernel 2.6.22-rc3 safe to migrate to?

Kernel 2.6.22-rc3 safe to migrate to?

[Justin Piszcz]

Wondering as their were a lot of XFS related issues early on in 
development..?  The 2.6.22-rc3 kernel has the core 2 duo coretemp patch by 
ruik which I want be running as long as 2.6.22-rc3 does not have any 
severe XFS issues?

Tracking -rc and running 2.6.22-rc3 for a couple of days now, no 
problems with xfs since this infamous 2.6.17 thingy[0]. But that's 
pretty useless information I guess, since your setup will be different 
from mine. Did you have anything "special" in mind when asking this?

XFS currently has a data-corrupting bug, where files which were appended
by small amounts may lose their updates on umount - I see this
corrupting hg repos. There's a patch which works for me, and is in
2.6.22-rc3-mm1, but it hasn't been merged upstream yet.

Ah that's it- and USB appears to be broken as well, I'll stick with 
2.6.21.3 for now.

Thanks!

Just for the record, you mean this one:
http://lkml.org/lkml/2007/5/12/93   ..right? (haven't been bitten by 
this one...yet)

Got any pointers? I'm using USB right now, one is i386 with 2.6.22-rc3, 
another one is powerpc, tracking -git and USB seems to work.

Sent this in another e-mail to LKML, it breaks support for my UPS:

I use nut-2.0.4-4 with a UPS attached via USB and from 2.6.21.3 -> 2.6.22-rc3 it
stops working, see below.  My .config is attached.

(works fine)

I also have seen this on -rc2-mm1, my APC UPS status was not showing up. 
  I haven't investigated in any more detail.

That's the one.  It's fairly subtle; there's no metadata/filesystem
corruption, and the file just reverts back to a previous length, so if
it were append-only, it would just return to a previous state.

Oh, good.  I hadn't read through the last couple of days of commits.

Nice, any word on the USB bug?
