[rtl] A strange problem!

[Hai Xu]

Dear all,   I met a very strange problem of RTLinux. My system is RedHat 7.0 + Linux Kerenl 2.2.18 + RTLinux 3.0 final. When I finish the installation of RTLinux 3.0, everything looks fine. So I use "rtlinux start" command to start the rtlinux. Then the strange problem happens. It says my uid is changed. When I use "whoami" to check my status, it says "whoami: cannot find username for UID 4294967295".(I login as root, so I think the uid should be 0)   Then I can not reboot or shutdown my computer. When I type in "reboot", it tells me as I am not a superuser, I can not do so. I then logout, try to restart the computer using the menu of login screen, but I just go back to the login screen. I have to reset my computer. After I tried several times, I found out that I just need to stop the rtlinux, then everything is OK. So I think maybe this problem is coming from RTLinux.   I hope you can give me some help about it.   Thanks in advance.   Hai Xu
