Okay. Is that 32-bit or 64-bit? How much RAM ? My PPC machine is not currently set up for Linux, and has only PCIX (not PCIe) slots, so I'll try this first on an x86-32 box with PCIe. If it works for me there, then I may be able to try a PCIX card in my PPC-32 box later. The PCIX card won't have a 7042 of course, so I'll use a 6081 instead. Those earlier Marvell chips are supposed to be extremely similar. > > ::: -- 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... > > a) mount /dev/sda3 /mnt/src > b) cp large_500Meg_file /mnt/src/. > > ========================================================== > ========================================================== > NOTE: this does NOT fail on a 2.6.11 kernel version!!!! > So I do NOT think it's a hardware problem! > > It could be a PEX related problem with arch/ppc - I would > expect under heavy pounding with smaller files it would > fail as well - but it does NOT) > ========================================================== > ========================================================== > > Anything else you need to know? > > - > To unsubscribe from this list: send the line "unsubscribe linux-ide" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
