https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D225791 Richard Paul <richard@primarysite.net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |richard@primarysite.net --- Comment #2 from Richard Paul <richard@primarysite.net> --- We're seeing this now since we migrated out instance between instance types= .=20 Before we were using a c5.9xlarge instance and we recently scaled that back down (we'd rebuilt and scaled up earlier in the year to deal with seasonal load). 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.=
