Hi,
during a make release run I got two panics in -CURRENT (from Feb 16).
Both panics occured during high I/O rates.
The first one occured while mkisofs'ing the resulting release CD tree,
The second one while rm -rf RELEASEDIR. I am now running a kernel from
Feb 08, which I believe is OK. I restarted a make release and will inform
you if this kernel also panics.
The relevant file system has soft updates enabled and was newfs'd with default
argumengs (just the inode count was reduced). Background fsck is turned off,
write cache is disabled. If you need more information, I can give additional
detail.
Thanks,
Daniel
