Hi,

4.15 was released on Sunday. Fedora will be following the same rebase procedure that we have in the past: After a few stable releases, typically 4.15.2 or 4.15.3, F27 will be rebased to 4.15 with F26 rebased shortly there after. I would expect this to happen by the end of February.

Note this was a tricky kernel release because of all the Spectre/ Meltdown work but that should be settled at this point. More testing is always appreciated though.

Updates are now filed. Note that the kernel-tools split has happened as well so please test that as well

4.15.2-300.fc27.x86_64 breaks my POE-switch with a DECT-phone booting with 4.14.18-300 and it immediatly comes back

when disconnect/reconnect the DECT device (Yealink W56P) i see a sequence of dhcpd-flood in the logs, IP not pingable while the dhcp-log talks about it hard-configured IP by MAC (192.168.2.15), handset says "line busy"

TV on the same port also not pingable while on the quad-port "01:00.0 Ethernet controller: Intel Corporation 82580 Gigabit Network Connection (rev 01)" it's reachable as usual

the software-switch is a dual-port PoE-card: 05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06) 06:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

what goes wrong are the ethtool-settings of "ifcfg-poe-phone" comment them out and all is fine

hardware and config unchanged for around 12 months so there must be some regression in the network driver
