[OpenAFS-port-darwin] OpenAFS 1.6.0_fc7: frequent kernel panics under OS X 10.6.8 on iMac12,2

Thu, 1 Sep 2011 15:09:10 -0400

Sirs/Madams

We are having difficulty running OpenAFS 1.6.0_pre7 under following:
1. OS X 10.6.8 with latest updates
2. iMac12,2, Core i7, 3.4GHz, 12GB RAM
3. default AFS client cache settings

[Interestingly, these same iMacs will not run OpenAFS 1.5.78 without enormo=
us delays (Finder and shell) when accessing AFS volumes.
OpenAFS 1.4.14.1 appears to run normally on these computers, however.]

We have 25 identical iMacs, each of which has/does/will kernel panic as sho=
wn below--often at Shutdown/Restart:

Has anyone else seen this behaviour with these most current iMacs?

With thanks as always,
