yup. assuming it's the same problem that we saw, then it'll boot once via PXE ok. however, after installing a node, then OSCAR then will try to reboot (I think), and that should fail at the PXE stage. pulling the power cord again should let it boot into the OS. a 'proper' fix/workaround is to build an e1000 driver from the src at http://e1000.sourceforge.net/ and drop that into both your OSCAR boot + install kernel and into your OS kernel (if they're different). cheers, robin >Thanks again, >Paul > >On Mon, May 19, 2008 at 5:00 AM, Robin Humble ><[EMAIL PROTECTED]> wrote: >> On Mon, May 19, 2008 at 01:03:34AM +0200, Salva . wrote: >>>nodes they seem to find the entry point for PXE but they never boot. >> ... >>>The hardware is a supermicro X7DWT. >> >> our X7DWT-INF boards (with SIMSO+) have a BIOS/hardware bug which means >> that we need e1000 driver version >= 7.6.15.4 before they will reboot >> reliably. >> >> the symptoms look to be similar to yours - the PXE server sees the >> requests from the node and replies, but the node never recognises the >> replies and so never gets any further. >> >> the problem goes away if the SIMSO+ (BMC management card) is removed >> from the system, or can be worked-around if you never 'reboot' or >> 'shutdown' Linux, but instead always IPMI reset or on/off the board. >> also unplugging the power from the board lets it PXE boot correctly the >> time after that. >> >> hope that helps. >> >> cheers, >> robin >> >> ------------------------------------------------------------------------- >> This SF.net email is sponsored by: Microsoft >> Defy all challenges.
