Fresh install of Ubuntu 12.04: live USB boots and works perfectly fine, but booting (in recovery mode) after installer finishes consistently results in boot to hang at:
ACPI: Requesting acpi_cpufreq
Refined TSC clocksource calibration: <XX> MHz
Switching to clocksource tsc
I've tried all kinds of clocksource= boot options, all resulting in the same behaviour (jiffies, acpi_pm) or a kernel panic (hpet). acpi=off also results in kernel panic. notsc removes the latter two clocksource lines, but booting still hangs at the same place.
During installation, I tried both "Install updates while installing" enabled and disabled. Tried with Ubuntu 12.04 and Ubuntu 13.10 with exactly the same results. Tried on two (identical) machines.
Hardware:
Dell Precision T1650
Intel Xeon CPU E3-1225 V2 @ 3.20GHz (current clock speed)
NVIDIA NVS 300
BIOS Version: A12 (Default settings; Legacy boot)
According to the ubuntu website, this should work just fine:

Any ideas?
