I decided to use a pre-compiled kernel, and installed 2.6.19-1-multimedia from this FTP site of Musix, a multimedia Linux distro based on Knoppix. Now, i have two serious problems when i boot from the new kernel. First, i can NOT open a shell as root or a user, Konsole gives me this error:

"Konsole is unable to open a PTY (pseudo teletype). This is likely due to an incorrect configuration of the PTY devices. Konsole needs to have read/write access to the PTY devices."

What does this mean and how do i fix it? Second, i can NOT get root access as a user, after i enter the root password, i get this error:

"The program 'su' is not found; make sure your PATH is set correctly."

What's wrong? I even installed two other kernels, one from the FTP site of Musix and one from your site, BOTH were version 2.6.21.5-rt18, but i STILL had the above two problems. I noticed whenever any of three kernels installed, i received this error:

"Hmm. There is a symbolic link /lib/modules/(version of kernel)
However, i can't read it: No such file or directory
Therefore, i am deleting /lib.modules/(version of kernel)"

Could this be the cause? Also, during bootup, instead of '...done' appearing when 'Waiting for /dev to be fully populated' comes up i get 'iTCO_wdt: Failed to reset NO_REBOOT flag, reboot disabled by hardware' followed by 'intel_rng: FWH not detected.' Is there anything i can do?
