Any reason for running a 32 bit kernel on this hardware and not a 64 bit (x86_64) kernel? > dmesg output .... > [ 295.334213] SGI XFS with ACLs, security attributes, realtime, large > block/inode numbers, no debug enabled > [ 295.389636] XFS (sda2): Mounting Filesystem > [ 295.459074] XFS (sda2): Ending clean mount > [ 299.575714] [Hardware Error]: Machine check events logged There's something going wrong with your hardware, it appears. This may or may not be related to the xfsdump problem, but you should find out what these errors are. Other than that, I need to see the complete output of xfsdump up to the point it is apparently hanging. When you think it has hung, can you provide the output of `iostat -d -x -m 5` for a period of about a minute to see if there is disk IO taking place? it would also be handy to know if there is any cpu being used at the same time... A snaphost of /proc/meminfo when you consider it hung would also be useful...
