But one has changed much between 4.9.13 and 4.9.25: kernel size and
configuration.
4.9.13 size was 6MB and 4.9.24 is 7.1MB. Many modules have been
compiled into kernel, here is shortened, but significant list:
- iptables (NETFILTER_XTABLES, IP_NF_FILTER, IP_NF_TARGET_REJECT)
- SATA_AHCI
- ATA_AHCI (PATA, what a heck?)
- FBDEV_FRONTEND
- HID_MAGICKMOUSE
- HID_NTRIG
- USB_XHCI
- INTEL_SMARTCONNECT
Modules that are not loaded are not used.
You got me wrong: these are compiled into kernel statically, not as modules...
More updates on kernel problems: 4.9.13 (no xen patches), recompiled with config
applied from 4.9.25, appears to be also faulty in my env. I'll try
to dissect config and compilation differences and try to isolate what went wrong there.
Trace included below.
