Hi, just a heads-up: 3.18.21 didn't boot up on HP ML310e Gen8 v2, SATA drives in AHCI mode, / on software raid 1, no LVM. It ended up in kernel panic with unable to mount root fs. Attached. No difference in grub kernel/xen settings.

I didn't investigate the things deeper so far. 4.4.3-3/3.18.17 is booting fine.

Any similar experience?

Check the module line for the initramfs is present in grub.conf. It's gone missing in all our recent upgrades, but I wasn't sure if it was an upstream problem or our own.
