Comment # 1 on bug 905863 from Bernhard Wiedemann

I can not reproduce the error here, even with your initrd.

Did you pipe the lsinitrd output somewhere (e.g. less or head)?

Can you still reproduce the problem?

IMHO it might not be a bad one anyway
because "Broken pipe" only means that someone is writing
but the output file-descriptor was already closed on the other end.
