Meanwhile I saw a patch fixing something in mm/highmem_32.c and tried 
4.12 release. And it works fine now, has been compiling more than 24h.

Still bisecting.

There are actually 3 failure modes:
1. these messages
2. just reboot
3. hang with task hung timeout ot startup or shutdown (during reboot) - 3 of 
these so far.

I have tried bisecting 1 and 2 together. So far I have this:

Additionally, 6a776e47a045 seems to be bad (just had failure during 
complation).

Some something between a6128f47f7940d8388ca7c8623fbe24e52f8fae6 and 
6a776e47a045 it seems.

Still bisecting.

There are actually 3 failure modes:
1. these messages
2. just reboot
3. hang with task hung timeout ot startup or shutdown (during reboot) - 3 of 
these so far.

I have tried bisecting 1 and 2 together. So far I have this:

Additionally, 6a776e47a045 seems to be bad (just had failure during

Some something between a6128f47f7940d8388ca7c8623fbe24e52f8fae6 and 
6a776e47a045 it seems.

successfully.

It booted on my physical machine too, and trouble happened during 
compilation on both CPUs with make -j2.

On next try it just rebooted.

Thanks.

So plain 4.12.0-rc7 booted all the way in the athlon guest here. So I
either can't reproduce in the guest or I need to try linux-next. Well,
tomorrow...

I can't reproduce this in a guest. Can you send .config please?

4.12.0-rc5+git: kernel BUG at arch/x86/mm/highmem_32.c:47

2017-06-24 Thread Meelis Roos 
This is 4.12.0-rc5-00137-ga090bd4ff838 on a dual AthlonMP server tha has 
been running fine until 4.11.0 included. 4.12.0-rc5-00137-ga090bd4ff838 
was the first kernel after 4.11 that I tried and the problem happened 
while compiling next kernel from git.

First it seems to be task jbd2/sda1-8:70 blocked for more than 120 
seconds with blk-mq (wondering why I have it enabled on a old spinning 
HDD server) and then series of invalid opcode:  BUG-s.

4.12.0-rc5+git: kernel BUG at arch/x86/mm/highmem_32.c:47

2017-06-24 Thread Meelis Roos 
This is 4.12.0-rc5-00137-ga090bd4ff838 on a dual AthlonMP server tha has 
been running fine until 4.11.0 included. 4.12.0-rc5-00137-ga090bd4ff838 
was the first kernel after 4.11 that I tried and the problem happened 
while compiling next kernel from git.

First it seems to be task jbd2/sda1-8:70 blocked for more than 120 
seconds with blk-mq (wondering why I have it enabled on a old spinning 
HDD server) and then series of invalid opcode:  BUG-s.
