Subject2.2.14pre9 : procfs oops
Hi

We are running 2.2.14pre9 on an 500Mhz Athlon box. All of a sudden
we couldn´t run any program chmoding in /dev/pts (i.e. kvt). It
exited with 0 after chmod failed with permission denied. We
examined straces, but still had no clue what the problem was when
it oopsed on init 1:

Unable to handle kernel paging request at virtual address 80000008
current->tss.cr3 = 08269000, %cr3 = 08269000
