Bug#878332: linux-armmp-lpae: Raspberry pi 2 hangs at boot

Show all headers | View raw

Package: linux-armmp-lpae
Version: 4.12+85~bpo9+1
Severity: important

Hi,

starting with kernel 4.12 (but I also tested 4.13 from sid). My Raspberry pi 2
hangs at boot with this. All I get at boot is this:

U-Boot 2017.09+dfsg1-3 (Oct 09 2017 - 22:14:03 +0000)

Appending "debug" to the kernel command line didn't show any other messages. I
can't enable EARLY_PRINTK as it depends on DEBUG_LL which is incompatible with
multiplatform :-(. How should I proceed now?

I would do some git-bisecting but I'm lost at which commit to start - I
obviously can't just start at commit 1 after 4.11.6 as it would take ages to
compile and test all the resulting kernels :-(


BTW: Updating u-boot didn't help either (this was my first hope)


Best,
Philip
