Subject: PS3 Storage Driver O_DIRECT issue
Date: Fri, 13 Jul 2007 14:27:52 +0200	[thread overview]
Message-ID: <20070713122752.GA854@aepfle.de> (raw)
In-Reply-To: <20070704132212.726923000@pademelon.sonytel.be>


This driver (or the generic PS3 code) has appearently problems with
O_DIRECT. 
glibc aborts parted because the malloc metadata get corrupted. While it
is reproducible, the place where it crashes changes with every version
of the debug attempt.
I dont have a handle right now, all I know is that the metadata after a
malloc area get overwritten with zeros.


Can you have a look at this? 
parted /dev/ps3da
print (a few times)
