FreeBSD freezes on: Trying to mount root from ufs:/dev/md0 and is stucked
Yeah – huge projects with different types of hardware always bring up many different type of problems: Today I had an INTEL Server Platform S7000FC4UR (really a fantastic System: 160GB of RAM, 4x INTEL Xeon X7350 with 4 Cores, 2,93Ghz, so the system has 16 Cores!) to boot up with FreeBSD 7.1.
The boot-process hang up at several points, but went further after a delay of 20 to 30 secs, till the following point was reached:
md0: Preloaded image 4194304 bytes at 0xffffffff80c4be40
Trying to mount root from ufs:/dev/md0
The boot process is stuck
After trying different boot-options and kernels, I disabled USB2.0 support in the Bios and – *whoop* FreeBSD was booting without any problems. ACPI also seems to have some influences – but the mainproblem is the USB 2.0 support. Due to the fact, that a keyboard is nearly as fast on USB1.0 as on USB2.0 the solution to this problem was quite ok for the customer
