I just recently started running 2.1 kernels. (Currently 2.1.89)
I noticed under /proc/cpuinfo That I my chips have the sep_bug. They are
stepping 2 150Mhz PPros. I have looked through the kernel source and found
the function in linux/arch/i386/kernel/setup.c that checks for the sep_bug
but there is no documentation on what it is.

What is the sep_bug, and should I be concerned about it.

Thank You,
Brad Snow
