Subject: 2.4.28 crashes with BUG at page_alloc.c:144

I'm having problems with a stock 2.4.28 kernel occasionally giving
BUGs and then the system becoming unstable.

Has anyone else seen this ?

Example:

A page being freed has the "mapping" pointer set:

if (page->mapping)
BUG();

Are you using any binary module? Seems so.
