weird console output

[Alexander Best]

very often when i boot or shutdown my pc i see weird text being output to the
console. to me it seems like 2 messages are being mixed into 1 message. here's
an example:

"WcAdR0N IaNtG : aWtIaT1N EbSuSs  o0p ttiaorng eetn a1b lleudn,  0e
xcpde0c:t  r<eHdLu-cDeTd- SpTe rDfVoDrRmAaMn cGeS.A-
H1W0ANR NJILN1G: DIAG2N>O SRTeImCo voapbtlieo nC De-nRaObMl eSdC,S Ie-x0p
edcetv irceed uc
ecdd 0p:e r3f3o.r0m0a0nMcB/es.
transfers"

i'm running FreeBSD moshnroll 8.0-CURRENT FreeBSD 8.0-CURRENT #20 r190162M:
Fri Mar 20 19:10:47 UTC 2009     root at moshnroll:/usr/obj/usr/src/sys/ARUNDEL
i386, but i've also had this issue under CURRENT. maybe this issue is smp
related?

cheers.
