Won't boot. udevd: worker not accepting message.

[linux guy]

I pulled the hard drive from my laptop and installed it in my server
and it behaves exactly the same way.

The drive itself is an SSD and it tests cleans.

Its not initramfs either... I only touched one kernel when I was
testing the nvidia driver.  None of the other kernels will boot
either.

Something in the last upgrade messed up the boot process.

Any ideas ?
