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...

Hi Claudio,

I have also used your preference pane but I have obtained immediately

the same kernel panic. Have you tested your software on an intel CPU?

Hi Enzo,

during development work of my afs preference pane, i started and

stoped

afs many time(for testing, the preference let do it). i didn't get any

kernel panic on 10.4.x but i have seen that after three or four afs

start/stop i can't get anymore to unmount afs(1.4.x and 1.5.x). I

have had

to restart osx. I thought tha probably was a bug on my application,

but i

have seen that it occour also calling afs script by and via terminal.

I think it can be a little bug on afs kernel extension...

Hi,

I have installed OpenAFS 1.5.2 on my MacBook Pro running MacOS X

10.4.10. At the startup the 'afs' volume is correctly mounted on my

desktop, but if I use  the script /Library/StartupItems/OpenAFS/

OpenAFS (start/stop) first  to unmount it and then to re-mount it ,

so I get a kernel panic. Below the related information contained  in

the panic.log file:
