dmesg after suspend/resume
My HP Pavilion dv4-1125br suspends and resumes correctly. However, the battery
information provided by ACPI disappears. Before suspend I can get battery
information in /proc/acpi/battery/BAT0/state. After the suspend/resume,
BAT0/state shows not present.
This is a fairly recent laptop, and this problem is present in Fedora kernels
as early as 2.6.27. I've found bug reports of this issue for Ubunto and Arch
Linux, so I don't believe it is Fedora specific.
