Hi Dave,
If a user by mistake issues the below command some junk characters are
printed on the console. (crash vmlinux.gz or any .gz file) Please
advise.
linux:/boot # crash vmlinux-3.0.10-0.7-default.gz
crash: ��{�UU����3ܣ@bjb
R�I-& ��
�c�"O9�Y��X^f<3��86���v1RS�q��\`������#��^����k�s@��}���= �׳d��g_�^{���Z{�����O-
F�-W|y�7���f9�k���g���: compressed file name does
not start with "vmlinux"
Use "-f vmlinux-3.0.10-0.7-default.gz" on command line to override.
crash: vmlinux-3.0.10-0.7-default.gz: not a supported file format
