Bug#562688: linux-image-2.6.32-trunk-686: Kernel WARNING for Acer TravelMate C300 in native_apic_write_dummy
Package: linux-2.6
Version: 2.6.32-2
Severity: normal
I found the kernel warning below in the system logs. It shows up very early in
the boot process but does not harm system operation. The same warning is present
in "Linux version 2.6.31-1-686 (Debian 2.6.31-2)" but I think was not in 2.6.30.
