(non fatal) segfault during boot loading IRD

[KarlGoetz]

I will attach dmesg, one from a rescue mode boot, and one from a standard boot.

In short, they both crash for teh first time ( i think) doing stuff related to IRD (i wouldnt like to guess what).
Its on a laptop - a Compaq Evo N1000C

this is the multi user boot.
I'm pasteing the relevent bit (i hope), with info each end whichi wasnt sure the relevence of:

this one looks like a dupe of bug 46947 , which is linked to from that
address... wonder why i didn't spot it.

Normally "fixed" bugs don't show in searches.
