"Last Trap MMU" errors when booting Linux on T2000 server

Hello,

I'm testing several Linux flavors on a Sun-Fire-T2000 server with System Firmware 6.7.4.

I have tested several Sparc64 linux distributions, and only Debian 5 (Linux 2.6.26) and Ubuntu Gutsy (2.6.22) boot over network (TFTP), rest of tested systems fails to ok prompt when loading kernel (before Linux execution) with error: "/packages/obp-tftp: Last Trap: Fast Data Access MMU Miss".

Do you know how to fix or debug it?

Thanks in advance!

Best

    That's not the least bit surprising.
    There are versions of Solaris 10 and OpenSolaris that won't function on the UltraSPARC T1 CMT architecture, either.

    I don't think there is anything you can do to tweak the OS's you have currently chosen to investigate. However, that would be a discussion that is better suited in some sort of Linux forum. Rewriting a kernel is outside the scope of the Hardware Forums.
