| |
This one snuck in...
* debugging message for ACPI
* Intel guys removed it from their 2.4 tree (at my request)
* it's point-in-time specific (message becomes nearly useless after ACPI bug fixes)
* b/c of the point-in-time issue, it's IMO much more appropriate for a vendor kernel (where the message, I agree, may be helpful)
* can potentially mislead users to the correct cause of root mount failure
* overall, I disagree with adding messages like this. The number one bug report, by far, for networking drivers is ACPI-related (no interrupts delivered). You don't see me adding "boot with acpi=off" messages to the net subsystem.
