I have the same problem on two builds of 5.2, one is a Sony Vaio PCG-F360 Laptop (PII 400MHz) and the other is a newer P4 system with Asus mother board. Both worked fine with 5.1 and both broke with 5.2. I was able to work around this problem by booting up with ACPI disabled. Is there a known issue with ACPI that is being worked on for 5.2 or did someone already submit a bug report?


Thanks,

David
