This instance is our primary db instance and the kernel panics seem to happ= en either during the db dump process (which occur when we have the least amoun= t of DB traffic) or as has happened once so far, during the peak of the daily lo= ad. Our log output is almost the same except as that already submitted, although out current process line reads: ```current process =3D 12 (irq269: ena0)``` The two previous reports had the same IRQ number and are on the same class = of instance types whereas we're on an M5 class instance type and get a slightly different IRQ number. Also, this was happening on 11.1p4 but we since upgr= aded to p10 and the issue still is occurring. I'm planning on upgrading a clone= to 11.2p0 later this week to check out whether there's a new version of the ENA (from here https://github.com/amzn/amzn-drivers/tree/master/kernel/fbsd/ena= ) in this build. --=20 You are receiving this mail because: You are the assignee for the bug.=
