Update
We just got hit by the soft lockup again. Now running 2.6.15-29.60.
Backtrace slightly different though.

Ok, further investigation here shows that this is not actually a
regression, just that the load on our server after the upgrade was
higher than earlier.
So, not a regression, but a general kernel bug during our extreme load
pattern here.

Thanks for the assurance Mattias. Just thought the question should be
raised as many normal desktop installations may well have some servers,
such as NFS, enabled. I have never had OoM errors previously on my two
Dapper PCs - if these do occur with the new kernel image then I shall
report back.
Roger Miller: There seems to be little cause for fear in normal
installations. Unless you are OoM:ing in heavy network usage, I don't
think you have anything to fear. Had this been a cause for concern for
regular users, this would have been handled much more "high-profile",
and with greater speed t
Is 2.6.15-28.55 safe for a desktop install? If not then suggest this
should be removed from repositories until issue resolved. A warning
should also be posted on ubuntuforums.org to help those who have already

The "downloader" is a part of application software that stages files
from remote sources onto an nfs-mounted filesystem. Typically 10-20
parallel streams in each downloader, and 10-20 downloaders running
during high load. Aggregate performance 20-80MByte/s, most of this with
large tcp windows.

Can you tell me what "downloader" is? Would also appreciate a full
dmesg, and please attach to this bug report (via web interface) as
opposed to an off-site link).
Thanks

Forgot to say, it is linux-image-2.6.15-28-server_2.6.15-28.53_i386.deb,
so server flavour on i386.
