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.
