From 06405df7a8da24b7d735b32454c7d3b1f2ebaabc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Mon, 24 Oct 2016 17:03:48 +0200 Subject: [PATCH] brcm47xx: bump kernel to 4.4 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Kernel 4.4 was ready for brcm47xx for almost a year now but I kept postponing the bump due to problems with Linksys WRT300N v1.0. OpenWrt and LEDE with 4.4 were hanging at the booting with the: > Starting program at 0x80001000 (the last CFE message). This was a permanent state, "make distclean" wasn't helping, I spent hours debugging this and I was reliably reproducing the issue every time. I also reported it on linux-mips ML in the thread: > BCM4704 stopped booting with 4.4 (due to vmlinux size?) After ~month I started working on WRT300N again. I got hangs as expected every time I switched from 4.1 to 4.4. I started experimenting with: 1) TRX content (I tried dropping rootfs partition) 2) BZ_TEXT_START of lzma-loader 3) Flashing other variants of image: lzma compressed kernel (without a loader), gzip compressed one, uncompressed one. At some point I got rootfs-less image booting and after that I couldn't reproduce problem anymore, even with a complete firmware. It seems like hardware was in some locked/unstable state that got magically fixed. I have LEDE working now, tested it even with "make distclean", it seems we can bump kernel now. I'll keep testing it on WRT300N for some time.
