I have no problems accessing from an x86 the ext3 partitions made from the
x86_64 host that are on the same physical disk as that problematic xfs one.
It's not the first time I try, with this exact same disk... last time I
gave up trying to read it from an x86 host, and when I tried looking into
the problem my x86_64 machine was having... gone, it was booting again, so
I just put the disk back in, and it worked fine.

Now, that x86_64 doesn't boot anymore (same problem), and I tried (again)
to access the disk's data from an x86 test machine, and I can mount the
ext3 partitions fine, I can even get the disk's grub to appear and the
kernels tell me that I need a 64bit system for them to work ;-) But trying
to mount that xfs partition (made on the x86_64 host running FC2) gives me
a segfault every time, which is why I was asking : I'm 100% sure my x86_64
FC2 host could still read that partition if it still booted, whereas no x86
FC2 or FCDev can, as I see it...

I've tried searching for info regarding possible incompatibilities for
filesystems between archs, but can't seem to find anything relevant to my

That's my laptop, a completely different matter :-)
