Network slowdown on lo0 introduced with svn186119/186121

[Li, Qing]

Hi Christian,
 
Is the loopback address or an address that is assigned to
an interface used by amanda? Would it be possible for you
to give me some information on the tests you performed and
on your method of measurement?
 
Thanks,

Hi!

Today I built a new kernel on current and experienced a massive network
slowdown on lo0 when doing a backup using amanda. I made some tests and it
seems that the commits 186119 and 186121 to the svn repository are causing
it. A kernel based on revision 186107 runs fine and all kernels starting with
revison 186119 do not.

This slowdown seems to appear only on the loopback interface, not on my lan
interface.

Is this a known issue?

Regards,
Christian.
