pgpwde Found an empty barrier:... We might crash here
I just installed pgp whole disk encryption a bit ago and I am now having a problem which seems to be associated with the /boot partition on the encrypted disk.
The system will hang on boot with a message along the lines of:
pgpwde: Found an empty barrier: ffff8803e2c44b40. We might crash here
I bring the system up with an alternate (un-pgp encrypted /boot partition) and I can run fsck on everything but the problematic /boot partition.
similarly, running parted on that physical disk also hangs
There are other pgpwde messages which seem to happen a on shutdown and startup, but don't seem to be associated with hanging:
pgpwde: Not sure what to do with action "change"
The system booted fine from this partition before, and I booted successfully a few times after full encryption w/o issues, but now there does seem to be a problem with this partition.
One additional peice of information, this did occur after doing a grub-install on this partition. That seemed to work correctly but I mention that in case this should not be re-run once the disk is pgpwde encrypted.
