In my case the issue was caused by an defective audio device driver from IDT.
I did find the issue by disconnecting all cables from the doccing station and then start and finish windows and start again.
Then I plugged in one cable and started the sequence start - shut down and start again
when i plugged in the speaker cable to the audio exit at the docking station the error came up at the second start,
after uninstalling the ITD driver the system started without problem the next time. hp than gave me the link to a differnt idt audio driver, that worked fine.
if you talk to hp: the case describing the problem was 4618947965
the correct driver was: ftp://ftp.hp.com/pub/softpaq/sp49501-50000/sp49590.exe but this might not be actual.
hope this helps!
