I'm experiencing the same crashes as Matt, but on 5.4-RELEASE-p3. The machine
is a HP DL380 G3 and it is heavily loaded (postfix mail server running
amavisd-new with antivirus and antispam, so it has heavy IO and CPU load). It
does not survive more than a couple of hours, while it is rock stable running
4.11. We have four machines like this, three of them are now again running
4.11 and we left the fourth one at 5.4. We have two other DL380 servers
working on our outbound mail queue, but they are not SMP and they are rock
stable on 5.4.
Without KDB_STOP_NMI, the machine was basically stuck after a crash.
Now I've finally landed in the kernel debugger and I have a trace from DDB and
have also been able to generate a crashdump with "call doadump".
If a developer is willing to investigate, I have:
- the vmcore file from the crash (its size is 1GB)
- the corresponding kernel, compiled with debug symbols
- a GIF of the console at the time of the crash with the backtrace at the time
of crash
- a dmesg from the box (see below)
- the kernel config file
Please contact me if you want to investigate this further.
Just in case, here is a dmesg from the box:
