From 28a88ff7e63bc9450a2b33eff48da9492d6e8670 Mon Sep 17 00:00:00 2001 From: Marcin FM Date: Wed, 16 Jul 2025 12:43:12 +0200 Subject: [PATCH] ramips: EAP615-Wall v1: fix bootloop by reducing LZMA dictionary Fix bootloop on TP-Link EAP615-Wall v1 by reducing LZMA dictionary size. Before this patch and after an upgrade to kernel 6.12 this device couldn't boot a kernel because of an error: "lzma compressed: uncompress error 1". I have chosen -d22 as dictionary size as suggested by @namiltd. The usual sizes for problematic devices are -d16, -d20, -d22. I have confirmed with my tests that this device can boot with a value up to -d27, but there is no size benefit from values above -d21, therefore -d22 is good enough.
