 I have just updated to actually RELENG_7 and after rebooting i found the
 following message in dmesg
 
 SMP: AP CPU c#d01  aLta uantcah0e db!u
 s 0 target 0 lun 0
 cd0: <HL-DT-ST DVD-RAM GSA-H54N 1.00> Removable CD-ROM SCSI-0 device
 cd0: 66.000MB/s transfers
 cd0: Attempt to query device size failed: NOT READY, Medium not present
 SMP: AP CPU #3 Launched!
 SMP: AP CPU #2 Launched!
 Trying to mount root from ufs:/dev/ad4s1a
 
 cd0 comes from the ATAPICAM Kernel option. Its really an atapi CD-Rom

 It's just that the messages are mixed up.
 From the first mail:
 
 (da0:umass-sim0:0:0:0): lGost EdOeMv_iLcAeB
 EL:( dLaa0b:eulm ass-simms0d:o0s:f0s:/0S)A:N SrAe_mEo2v0i0nPg
 rdeemvoivcee de.ntry
 
 ->
 
 (da0:umass-sim0:0:0:0): lost device
 GEOM_LABEL: Label msdosfs/SANSA_E200P removed.
 (da0:umass-sim0:0:0:0): removing device entry
 
 From the 2nd mail:
 SMP: AP CPU c#d01 aLta uantcah0e db!us 0 target 0 lun 0
 
 ->
 
 SMP: AP CPU #1 Launched!
 cd0 at ata0 bus 0 target 0 lun 0
 
 I've seen similar messages here, and someone has reported before.
 But they're not harmful. Although it's not so beautiful.

State-Changed-When: Sun Apr 5 09:44:56 UTC 2009 
State-Changed-Why:  
This is not a PR, the thing that happends is that the messages are not 
serialized but printed over eachother giving "weird" output. Currently 
there is no mechanism in place to correct this... Thanks for trying to 
make FreeBSD better!
