I updated kernel from 2.0.27 to 2.0.28. After a while after a reboot syslog begins to fill with error message:

xxxxxx kernel: Cannot read proc file system

/proc file system do exist, it is mounted and it has support compiled in the kernel.

Something broken?

Commented:
It sounds like you compiled /proc support as a module --
I'm afraid you need to go back and select "y" rather than
"m" for /proc support -- This will take care of the problem.
I ran into this one myself -- I could have sworn I had
compiled it directly into the kernel, but when I went back
through (slowly) and made sure it wasn't a module, it worked
fine.  You can use 'make xconfig' to bring up a nice TCL
interface in which case you can simply shoot right over to
filesystems, check the appropriate box, and rebuild.

Alternatively in /usr/src/linux/.config you can just toggle
that bit, and rebuild if you're like me, and don't care for
going through endless menus.  Good luck, CB.
