Description Chris Denice 2014-12-09 19:58:16 CET

Description of problem:

In my logs, and at boot, I can see a lot of error messages procuded by visor* modules (see below).

In /etc/modprobe.d, I have a file "visor.conf" with:
blacklist visor
blacklist visorchannel


So, it seems that the blacklist command is not honoured on our current Cauldron :-/

You have not blocked visorutil wich is the first module spamming...

 and it probably contains code that loads s the visorchannel module, something the modprobe blacklist wont prevent

Comment 3 Chris Denice 2016-07-15 11:36:54 CEST

Thanks, funnily enough, I only sorted this out very recently :)

The visor chain of modules is triggered by visorbus and visorhba, which goes into initrd. So even a blacklist a posteriori does not work, one has to regenerate the initrd with a proper blacklist lists, or wait for the next kernel to debug the blacklist :)

Here a working blacklist for visor:

cat modprobe.d/visor.conf

blacklist visorbus
blacklist visorhba
blacklist visorchipset
blacklist visoruislib
blacklist visor
blacklist visorutil
blacklist visorchannel

Don't know if we need to include it though.

Mass-reassigning all bugs with "kernel" in the Source RPM field that are assigned to tmb, to the kernel packagers group, because tmb is currently MIA.
