Could you please pass it through ksymoops so that we get an idea about the function causing this ? What was the last version not causing it ? hf32.4 ? If so, then the bug must be in one of the 8 patches. I've reread them but nothing obvious gets noticed.
This looks like a structure member gets accessed while a pointer is NULL, if you always get 0x88... I would be it could come from 2.4.32-ext3-link-unlink-race-1, but that would be strange.
Thanks in advance, Willy
