kernel BUG at mm/vmscan.c:606 invalid opcode: 0000 [#1]

[Karthik <molecularbiophysics@gmail.com>]

Is the following a problem with memory or a bug?

Linux-2.6.18-rc6 with suspend2 - version - -2.2.7.5

My Pentium M - 1.6GHz HP laptop. X- windows crashed suddenly and login
window came back again. I logged it but after a few minutes the whole
system froze and I had to hard boot..

Many thanks...

Karthik
