Summary: ACPI Exception (battery-0216): AE_SUPPORT, Extracting
_BST [20070126]
Kernel Version: 2.6.21-1.3200.fc8
Status: NEW
Severity: high
Owner: [EMAIL PROTECTED]
Submitter: [EMAIL PROTECTED]
I've had the exact same problem with many many different kernels (also on the
knoppix live dvd). Fedora people could not offer any help.
I cannot even find out whether it's a software or a hardware fault.
Distribution: Fedora 7
Hardware Environment: Acer Aspire 1640z
Software Environment:
Problem Description: Getting a battery exception right after HAL daemon is
started. Makes system unstable (usually it freezes within several minutes)
Steps to reproduce: Just booting, doing nothing special.
dmesg fragment:
