When installing freebsd (7.2, 8.0 betas, rc1, rc2 - AMD64) on a Clevo M540SR laptop (chipset VIA VN896), after menu option selection, the boot process freezes at "Trying to mount root from ufs:/dev/md0". On verbose booting it freezes giving some mode information: md0: Preloaded image 4194304 bytes at 0xffffffff80c4be40 ATA PseudoRAID loaded flowtable cleaner started warning: no time-of-day clock registered, system time will not be set accurately Trying to mount root from ufs:/dev/md0 Start_init: trying /sbin/init Start_init: trying /sbin/oinit Start_init: trying /sbin/init.bak Start_init: trying /rescue/init Start_init: trying /stand/sysinstall I've tried already several boot hints (any of them with success) such as: apic.0.disabled = 1 sio.0.disasabled = 1 sio.1.disabled = 1 fdc.disabled = 1 kbdmux.0.disabled = 1 A possible solution I found over the internet would be to disable USB 2.0 support on bios, but bios options are very limited and won't allow me to do that. FreeBSD 6.4 install and later upgrade to 7.0 went flawlessly, but upgrade to 7.2 brings up the freezes again on boot.
