5.3-BETA2 boot problem

Hi, 

I could not decide which list to post, so here it goes. 

I do not know if it's me or something else, but I can not boot with recent 
sources. 

I have FreeBSD 5.3-BETA2 #0: Tue Aug 31 22:36:53 EEST 2004 sources with 
cvsup. This kernel locks during boot. BETA1 locked previously, too. By 
"lock" I mean console keybord lights are freezing. Keyboard does not work. 
Screen stays same. Only reset from case or re-cycling the power helps. 

There is no core dump or log. I wrote below from verbose output. 

After initializin "lo0" there is two times below text and system locks:
 ---
ata0: reinit channel ..
ata0: reset tp1 mask=03 ostat=50 ostat1=50
ata0-master: stat=0x50 err=0x01 lsb=0x00 msb=0x00
ata0-slave: stat=0x10 err=0x01 lsb=0x14 msb=0xeb
ata0: reset tp2 stat0=50 stat1=10 devices=0x9<ATAPI_SLAVE,ATA_MASTER>
ata0: resetting done ..
 --- 

I do not have with my old current kernel which is built and have codes 
nearly the same date:
FreeBSD 5.2-CURRENT #0: Thu Jul  1 22:40:57 EEST 2004 

Hope this helps to find problem. 

Regards,
