[Bug 1396187] Re: Biosdevname does not generate expected interface names

[Kamil Madac]

** Description changed:

  After upgrade from 12.04 LTS to 14.04 LTS we lost consistent Ethernet
  interfaces names. We expected em1,2/p1p1,.. names, but we had
  eth0,eth1,...
  
  For some reason when I executed
  
- /sbin/biosdevname --nopirq -i eth0 
+ /sbin/biosdevname --nopirq -i eth0
  it returned nothing
  
- /sbin/biosdevname -i eth0 
+ /sbin/biosdevname -i eth0
  returned p1p1
  
  It turned out that problem was in file
  /lib/udev/rules.d/71-biosdevname.rules
  
  we removed --nopirq parameter from line:
  PROGRAM="/sbin/biosdevname --smbios 2.6 --nopirq --policy physical -i %k", NAME="%c",  OPTIONS+="string_escape=replace"
  to
  PROGRAM="/sbin/biosdevname --smbios 2.6 --policy physical -i %k", NAME="%c",  OPTIONS+="string_escape=replace"
  
  and it started to work as we expected. In 12.04 LTS there was no
  --nopirq parameter in file 71-biosdevname.rules.
