Gentoo kernel sources marked stable are: 2.6.32(-r29) 3.0.17(-r2) 3.1.10(-r1) Kernel 3.2.1(-r2) is also marked stable here, but I lost ethernet after upgrading to it, so I masked it here. In other words; kernel-2.6.32, kernel-3.0.17, or kernel-3.1.10 all seem pretty stable here. -- Roger http://rogerx.freeshell.org/ _______________________________________________ pvrusb2 mailing list [email protected] http://www.isely.net/cgi-bin/mailman/listinfo/pvrusb2
