After rolling back k8s-node1's kernel to 6.8.0-117 + spoofing
/etc/os-release to 24.04 so the operator picked the matching
ubuntu24.04 driver image (everything per the workaround documented in
docs/known-issues.md), the driver container still went into a restart
loop. Container status:
lastState.terminated: { reason: "OOMKilled", exitCode: 137 }
The driver-installer was hitting the namespace LimitRange default of
128Mi during `apt-get install linux-headers-6.8.0-117-generic` — the
last log line on every restart was "Installing Linux kernel
headers..." before SIGKILL. 2Gi gives apt + the DKMS compile step
enough headroom; peak observed during a successful compile in a test
container was ~1.4Gi.
