Package: src:linux
Version: 4.9.168-1
Severity: critical
File: /boot/vmlinuz-4.9.0-9-686
Justification: breaks the whole system
Dear Maintainer,
Debian 9 fails to boot on a Soekris net5501 with a Geode LX processor.
Debian 8 worked fine. Running Debian 9 on Linux 3.16.0-8-586 from Debian
8 works. (That's what I'm running Reportbug on.) Linux 4.9.0-7-686,
4.9.0-8-686 and 4.9.0-9-686 appear to hang early in the boot process.
The disk activity light remains lit when the system hangs. I'm attaching
a boot log acquired over a serial console.
I'm reporting this against the kernel because replacing only the kernel
works around the problem, but it looks like SystemD has been started
when the hang occurs, so I suppose a userspace issue can't be completely
ruled out.
Given that a kernel compiled for i586 works and one compiled for i686
does not, one might suspect that the processor isn't i686-compatible.
This seems to be rather unclear. According to the release notes this
processor should still be supported. It has all of the flags that this
script tests for:
https://www.debian.org/releases/stretch/i386/release-notes/ch-information#i386-is-now-almost-i686
On the debian-user mailing list, some people say that support for Geode
LX has been dropped. Others say it should work. If it is actually no
longer supported, then please reassign this bug report to the release
notes. In that case the release notes should be updated to document
this, and provide an accurate test.
As near as I can tell this processor is a Geode LX 800. The bios boot
screen calls it "Geode LX 500 MHz". It looks very much like this:
