I seem to have the same problem with Ubuntu Dapper 6.06 AMD64 on an A8N- SLI Premium + Areca 1220 controller.
Errors: - invalid ELF headers - general protection errors - segmentation faults files affected: /lib/libm.so.6, /bin/cat, probably more .... -- currently included arcmsr module causes file corruption on amd64 https://launchpad.net/bugs/45679 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
