#19192 closed defect (fixed)

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

Description

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.

Sorry, I missed a spot. Here's a new patch:
http://nbd.name/ltq-adsl-fix-v2.patch

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

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