Bug Description
I clicked the back button on the firefox browser after i watched a video. Only two programs were running: firefox and amule.
I attach the syslog. There are several warnigs:
-BUG: soft lockup detected on CPU#0!
-Eeek! page_mapcount(page) went negative! (-1)
-kernel BUG at mm/rmap.c:588!
-BUG: scheduling while atomic: python/
I'm using ubuntu 7.04 with the 2.6.20-16-generic kernel.

This bug may be a duplicate of #123223. Very same behaviour, as I had the same problem also when browsing with Firefox but on a 2.6.22-13 kernel.
This may show that the bug is older than 2.6.22.
