unfortunately they dont solve it:

 [   92.042586] Freeing unused kernel memory: 328k freed
 [   92.091838] khelper used greatest stack depth: 6244 bytes left
 [   92.281738] init[1]: segfault at 00000004 ip 49471cbb sp bff8dbb0 error 4

 [...]
 [   97.312484] printk: 611046 messages suppressed.

32-bit, PAE and RAM above 4GB seems to be enough to trigger that bug.
