Hi all,
after cvsuping today and a "make world" my kernel did a panic:
.....

done
Uptime: 18s
Automatic reboot in 15 seconds - press a key on the console to abort
The next boot with the same kernel is OK because the JAZ-drive (da5) responds
immediately to the INQUIRY command (The jaz needs some time to spinup the
disc inside the drive).
Before the MFC of the new ahc driver this did not happen.
Regards.
