[OpenAFS-port-darwin] Kernel Panic unmounting and re-mounting afs file system

[Claudio.Bisegni@lnf.infn.it]

Hi Enzo,
yes i use it on my MacBook Pro, and work well. For start/stop log/unlog
AFSCommander work as bridge to unix script. I have hardcoded the afs
startup script in app with cocoa class for launch unix process.
Try to download the last update of it i made some fix. Now it work well...
i hope..:-) Thank for bug reporting.

for your kernel panic i think that it is to associate with problem that
you have also with afs standard script. For me AFSCommander work well. In
September i'll code klog/aklog and unlog directly with afs api, after that
i'll try to mount afs and loading kernel extension by osx api. It's no
difficult but i don't have much time for it:-(.

Anyway i think that you must suppliy more information about your machine
state and configuration for your afs problem. How i have wrote in last
mail, i think there is some little but in kernel extension. The error that
i had accour sistematicaly. I'll try to indagate more on this issue.

For AFSCommander bug repory you can write me directly.
Thanks for reporting...
