Dear List!

I have such a problem (or is it a problem?):

# dmesg | grep da0
da0 at twa0 bus 0 target 0 lun 0
da0: <AMCC 9650SE-8LP DISK 4.06> Fixed Direct Access SCSI-5 device
da0: 100.000MB/s transfers
da0: 1430481MB (2929625088 512 byte sectors: 255H 63S/T 182360C)
GEOM: da0: corrupt or invalid GPT detected.
GEOM: da0: GPT rejected -- may not be recoverable.
Trying to mount root from ufs:/dev/da0s1a

System is 7.0 amd64. Just a fresh install. The problem appeared with 
sysinstall. The message appeared:

"WARNING:  A geometry of 182360/255/63 for da0 is incorrect.  Using  a 
more likely geometry.  If this geometry is incorrect or you are unsure 
as to whether or not it's correct, please consult the Hardware Guide in 
the Documentation submenu or use the (G)eometry command to change it now."

Never seen something like this before, when installing FreeBSD. Do not 
see eny 'Documentation submenu' in sysinstall.

How can I fix it? Everything seems to work OK, exept these messages. I 
am just about to build world and new kernel...

regards,
O.K.
