Kernel 4.12 restart during boot
Closed this issue · 3 comments
First I compiled with standard kernel using these commands:
mkdir android-x86 cd android-x86 repo init -u http://scm.osdn.net/gitroot/android-x86/manifest -b marshmallow-x86 repo sync --no-tags --no-clone-bundle export PATH=/usr/java/jdk1.7.0_80/bin:$PATH . build/envsetup.sh lunch android_x86_64-user m -j6 iso_img
Boot on my Positivo ZX3020 (CPU Z3735G) o.k., but no touch screen.
Linux (CentOS) with kernel 4.12 has touch screen working on this tablet.
I did new compilation inserting the commands
cd kernel git remote add maurossi https://github.com/maurossi/linux git fetch maurossi kernel-4.12 git checkout FETCH_HEAD cd ..
after repo sync
.
Booting in debug mode, the tablet restart after second exit.
Only a few lines appear and the screen becomes black immediately so I am unable to read anything.
Am I doing the compilation the right way?
How can I get detailed debugging log?
The line feeds of the command sequence got lost, here they are again:
`mkdir android-x86
cd android-x86
export PATH=/usr/java/jdk1.7.0_80/bin:$PATH
repo init -u http://scm.osdn.net/gitroot/android-x86/manifest -b marshmallow-x86
repo sync --no-tags --no-clone-bundle
cd kernel
git remote add maurossi https://github.com/maurossi/linux
git fetch maurossi kernel-4.12
git checkout FETCH_HEAD
cd ..
. build/envsetup.sh
lunch android_x86_64-user
m -j4 iso_img `
Hi,
I'm having similar problem with kernel-4.13 and kernel-4.14rc(s)
with oreo-x86 (where in principle swiftshader should allow booting for any non drm HW accelerated like VESA boot option),
but during kernel release cycles I remember I could boot nougat with kernel-4.12 and kernel-4.13
I tried several times to submit dmesg commands without success, I need to try to use serial console with Null modem cable to see if I can get message output
I my case reboot happened with all GPUs and also in normal boot (not associated to DEBUG).

LineageOS compiled with kernel 4.15 resolves this issue.
...
repo init -u git://git.osdn.net/gitroot/android-x86/manifest -b nougat-x86 -m cm.xml
...
git fetch maurossi kernel-4.15
...
Touch screen is working now.
