Public bug reported:
Binary package hint: hal
Hey Guys,
I have been through all the discussion on "Failed to Initialize HAL"
errors and I have not found a solution for my problem. I have had Ubuntu
8.04 installed on my machine since the official release of the beta.
About four days ago a new wave of updates came and one of those updates
caused this error message when I restarted the PC. I have tried a clean
installation and then updating and I get the same error. I also tried
another clean install and updating everything except hal and I get the
same error. It only happens on my desktop and not my VMs or laptop.
Desktop Hardware:
Intel Core 2 Duo
2gb ram+
nVidia 7900GS
PCHDTV Inc. HD-5500 (Could be the problem here)
I have attached the dmesg output. There's a very nasty exception in
there, here's an excerpt:
