I am seeing a major memory leak on a simple laptop i7 10th gen where the
system exhausts memory and wedges to a point where it must be recovered
with a power cycle, despite having physically 16GB RAM. With 8GB zram
swap and 16GB disk (SSD) swap for a total of 24GB, that only delays
memory exhaustion.
The problem manifests with kernel 6.8.0-78 on Ubuntu 24.04, but
reverting to 6.8.0-71 fixes it. Using -71, there is effectively no
memory stress in normal operation:
# uptime ; free
16:59:45 up 4:38, 1 user, load average: 0.77, 0.70, 0.79
total used free shared buff/cache available
Mem: 16036848 9602476 357320 3906440 9568068 6434372
