Subject: stack overflow in printk_all_partitions.
Date: Wed, 9 May 2012 15:58:48 -0400 [thread overview]
Message-ID: <20120509195848.GA961@redhat.com> (raw)
Szymon (cc'd) reported this oops that prevents his machine booting
a 3.3.4 kernel.

His partition tables don't look anything out of the ordinary to me.

Any ideas what's going wrong here ?
