And most of them have been changed since. Zlib remains high on the
list, but those paths are from /lib/inflate.c, during bootup.

What remains to be analysed is the recursions. If someone seriously
wants to work on those, I can respin the tests. The process is not
fully automated, so it will take me a weekend (and this weekend is
scheduled for a party).


The SCSI layer needs to be checked. I reproduced another crash on today on an older Niksun box running off the end of the stack.


It's somewhere in the scanning code. There's a case where it runs off the end of the stack. Check the compaq drivers for SATA as well, they also crash in a similiar place during bus scan. Both occurred during bootup, so I wasn't able to get a log of the particulars. Should be easy to reproduce. Compaq Presario 2200.
