Are you mapping the SRAM *OVER* the lower 2MB of address space? If so, then you won't have 34Mb of ram, you'll have 32Mb, and Linux may well be running off the end under stress. My memory is that you can move the vector table to another address. Wouldn't that be easier? - -- ] Michael Richardson Xelerance Corporation, Ottawa, ON | firewalls [ ] mcr @ xelerance.com Now doing IPsec training, see |net architect[ ] http://www.sandelman.ca/mcr/ www.xelerance.com/training/ |device driver[ ] I'm a dad: http://www.sandelman.ca/lrmr/ [ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) Comment: Finger me for keys iQCVAwUBQtJ7yoqHRg3pndX9AQF+eQQA0QBhaZAjq3vDQm8glqV0j+jmzO9+7U0m aZvOt5FsXu2mv3lS/2FySIQf3UuRcl0lIR5zaNfyn+I11K0YlfZvXgY97U2TMcmu 1K5sod0j3DpaIrK/a+VyWa+tQFe9zoPktazinVoQm4+geNRlTZf9P5XyYwXE7knn +TOTFRzLq7c= =iPOS -----END PGP SIGNATURE-----
