After successfully installing and operating a DEC Multia with RH Linux 5.2 Alpha, the following error messages appear when typing any command on any system console: command: unimplemented OSF mmap flags 0402 These messages do not appear in xterm or kterm (KDE).
This sounds like you are using a bash that was compiled for OSF/1 rather than Red Hat Linux. You might want to reinstall the bash rpm from 5.2: rpm -U --force bash-1.14.7-13.alpha.rpm and see if your problem persists after doing exec /bin/bash FWIW, I've never heard of an occurence of this problem here at Red Hat.
