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
