It seems that having a Myrinet 2k board plugged into any slot of the second PCI bus of the ES40 make the system freeze with 4 GBytes of RAM when doing cat /proc/pci. I just plugged the board back into one slot of PCI 0 and it works again. Why does it work with Tru64 and not with Linux ? I don't know. Thanks to Andrea Arcangeli for helping me understand there was something with the second PCI bus. ---------------------------------------------------------------------------- -- Sebastien CABANIOLS COMPAQ France HPTC Engineer CustomSystems & Solutions Annecy High Performance Technical Computing Office No. +33 (0)4 50 09 44 10 Fax No. +33 (0)4 50 64 01 39 Email.
