#19192 closed defect (fixed)

lantiq/Buffalo WBMR-HP-G300H high loadaverage leads to multitude of problems

Reported by: finas Owned by: developers
Priority: normal Milestone:
Component: packages Version: Trunk
Keywords: Cc:


Commit 44346 makes the router jump from a loadaverage of 0.something to 3.something.

  • With this commit it's almost impossible to do a dsl_control status. ( takes about 10 minutes )
  • Luci overview page does not update
  • the router is sluggish
  • DSL takes a long time to sync.

I nailed this down to commit 44346. a build of 44345 or prior works perfectly. Any build past 44346 ( or 44346 ) exibits this problem.

All these problems seem to come from this particular commit.

did you try the very latest version with linux 3.18?

comment:2 Changed 3 years ago by finas

not the very very latest. I tried quite a few from last week, lastest was 11 of March, cant remember the build, all with 3.18.

I can try one from today, if you wish!

Same problem here. I personally tried 44396 and 2 more, all well into 3.18.

The closed ticket mentioned at the top( /ticket/19144.html ) contains part of the detective work that nailed the problem to r44346, that contains dsl driver changes targeting kernel 3.18.

just tried latest trunk with the supplied patch and problem remains :(

CHAOS CALMER (Bleeding Edge, r44841)
root@router:~# uptime
12:22:23 up 11 min, load average: 2.95, 2.08, 1.05
root@router:~# uname -a
Linux router 3.18.8 #2 SMP Mon Mar 16 12:02:58 WET 2015 mips GNU/Linux

built after a make clean.

Sorry, I missed a spot. Here's a new patch:

No need to run make clean after it, just revert the old one, apply the new one and run make

comment:8 Changed 3 years ago by finas

load average is back to normal, dsl syncs at normal speed, luci overview page updates normally.

Great! Load average on my system went further down than it was with 3.14 :-) Thank you for the very quick fix!
