Hi,
I'm seeing a panic: ffs_valloc: dup alloc.
Does anyone have a similar panic?
The kernel is -current from March 15.
I cannot repeat the panic reliably, but it seems to occur after
suspend/resume (immediately or several minutes later).
The panic occured in /home, which is a ffs on cgd on wd.
"fsck -f" does not report any error on it.
