I have gotten it to boot from those hard-drives and it has the same behavior: Copying a large file to the same partition (>150MEG) causes the system to hang (no I/O - no input/output - nothing - complete freeze - like a primary resource is locked up or interrupts got completely & totally turned off in an ISR and its pending for something? Only way to get out of this is to power-cycle the box! @#$@#$#@ -----Original Message----- > ::: Can you give me exact details of how to set up and reproduce this? > ::: -- Kernel version > > Linux-2.6.23.1 > > NOTE: I am using ppc (arch/ppc instead of arch/powerpc) > > ::: -- number/config/model of drives > > 2x250GIG Western Digital - 3 partitions (largest (/dev/sda3 > ~200Gig - formatted to ext2). > > 7042 PEX on a MPC8548 Board > > ::: -- exact command line sequence to cause the failure > > NFS mount root file system (I am currently rebuild to take away > the NFS file system dependency) - /dev/sda3 is drive in question... .. MMmm.. I'd like to see that again without the rootfs-on-NFS. What exactly do you mean when you say "it just hangs" ?
