Strange boot messages under 6.0-STABLE

Aleš Rom
During boot process under 6.0-STABLE I spoted some strange messages.

...
...
Nov 14 18:18:45 romcek kernel: cd0 at ata1 bus 0 target 0 lun 0
Nov 14 18:18:45 romcek kernel: cd0: <SONY DVD RW DW-Q28A KYS1> Removable
CD-ROM SCSI-0 device
Nov 14 18:18:45 romcek kernel: cd0: 33.000MB/s transfers
Nov 14 18:18:45 romcek kernel: cd0: Attempt to query device size failed:
NOT READY, Medium not present
Nov 14 18:18:45 romcek kernel: Trying to mount root from ufs:/dev/ad4s1a
Nov 14 18:18:45 romcek savecore: reboot after panic: page fault
Nov 14 18:18:45 romcek savecore: no dump, not enough free space on
device (143858 available, need 523842)
Nov 14 18:18:45 romcek savecore: unsaved dumps found but not saved
Nov 14 18:22:01 romcek /usr/libexec/save-entropy[722]:
/var/db/entropy/saved-entropy.8 is not a regular file, and therefore it
will not be rotated. Entropy file harvesting is aborted.
.............

That "reboot after panic" message is strange, because the box is running
normally.
Can someone plese tell me why I'm geting those messages.

My system is 6.0-STABLE and I upgraded from 5.4.

FreeBSD 6.0-STABLE #4: Sun Nov 6 14:09:42 CET 2005

Your system panicked at some point in the past, but it can't save the
dump for the reason specified.

Also, the message about entropy is important and should be attended to.

Note that if you're never going to attempt to recover this crashdump you
can clear it by running 'savecore -c'.

If you just want to prevent the message from printing at the next boot
time, run 'savecore -c'.  If you want to try and retrieve the dump,
you can specify an alternate location to save the dump on the savecore
command line.
