Re: [CentOS-virt] NIC Stability Problems Under Xen 4.4 / CentOS 6 / Linux 3.18

Have you tried to eliminate all power management features all over? Are the devices connected to the same network infrastructure? There has to be something common. I've been using Intel NICs with Xen/CentOS for ages with no issues. Karel On 27.1.2017 02:57, Kevin Stange wrote: On 01/26/2017

[CentOS-virt] 3.18.21-16 upgrade, kernel panic, unable to mount root fs

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.

Indeed, a good catch. Module initramfs line was missing at 3.18.21 grub config. Thanks! -- Karel On 1.11.2015 21:46, Sarah Newman wrote: On 11/01/2015 12:07 PM, Karel Hendrych wrote: Hi, just a heads-up: 3.18.21 didn't boot up on HP ML310e Gen8 v2, SATA drives in AHCI mode, / on software
