From: Hauke Mehrtens Date: Sat, 13 Jun 2009 21:20:53 +0000 (+0000) Subject: Port to kernel 2.6.30. X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=74705fe7eba537db3df45cd0e9cf703370d358ab;p=openwrt%2Fstaging%2Fjow.git Port to kernel 2.6.30. There is an error in the unlzma system in the kernel. A lzma compressed squashfs filesystem does not work for me. This should compile and works for me on my Asus WL-500GP, please test it on more systems.
