Hi, I was playing around with Gnome when I got this Kernel BUG in my syslog. Kernel is 2.4.0 running on updated RedHat 7. My box is a Pentium III (440BX) with 256 MB RAM. System just froze, I could not move the mouse or switch virtual console, after hitting SysRq repeatedly the system finally shutdown. Feb 1 00:22:05 osho kernel: kernel BUG at page_alloc.c:72!
