Oops with reiser4 on x86_64

Oops with reiser4 on x86_64

[Hamish Rodda]

Hi,

I just started using reiser4 on my AMD x86_64 computer running debian pure64 
and a custom compiled 2.6.8.1-mm4 kernel, with reiser4 compiled in but no 
debugging.  I got an oops while copying 6G of smallish files using cpio (5G 
was completed); fsck reports "FS is consistent", I haven't tried to reproduce 
the problem yet.  I realise reiser4 is only tested on i386 so far but I 
thought you might be interested anyway:
