    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
    [ 92.288761] init[1]: segfault at 00000004 ip 49471cbb sp bff8dbb0 error 4
    [ 92.295763] 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.
