Hello,
Can anyone assist with this problem? I'm seeing a hang very early in boot under both 2.4.27 & 2.4.28-rc1.
When the kernel begins to execute the system hangs with ERROR: Invalid Checksum. This seems to be ACPI related. The HW is HP DL360G4. Any help is appreciated. Here is the console output:

I've tried several different things including disabling ACPI in the kernel, erasing NVRAM, etc. No luck.

Thanks,
