Hi Aqeel,
The reason that this is happening is the version of libc that you
compiled against from that Alpha workstation requires a 2.6.X kernel
and the syscall emulation portion of the simulator reports itself as
having 2.4.X version. That is the panic message is being reported
from the libc you compiled against. You could either compile with a
older version of libc or try to change the version reported in src/
arch/alpha/linux/process.cc to 2.6.something. I don't know what other
changes the syscall interface underwent when this happened, so to
make it work you may have to implement some new syscalls or change
some other things.

Hello,
I am having trouble running programs in SE mode. I compiled a
binary on an Alpha workstation running Gentoo linux, with kernel
2.6.21 and gcc 4.1. When I run the binary in m5, I get the
following output:

Can anyone help me fix this?
Thanks,
