Hi
I get this kernel panic during modest KVM load
kernel BUG at kernel/hrtimer.c:1236
abrt info
abrt-cli list --since 1526931546

I run 2 Supermicro X9SRL-F with cpu E5-1602 and validated Samsung ECC 32G memory. Supermicro has not yet released any spectre/meldown BIOS updates.
The kernel bug seems to be known, it's hidden at upstream customer portal.
Anyone that has clues or suggestions regarding this bug?
Regards, Henrik

Hi
I went back to kernel 3.10.0-693.21.1.el7.x86_64 and it runs stable.
