Subject: [PATCH 2/2] Revert "EDAC/i5000: Mark as BROKEN"
Date: Wed, 11 Nov 2026 15:25:29 -0800	[thread overview]
Message-ID: <20261111232529.407154-3-andrew.luebke@gmail.com> (raw)
In-Reply-To: <20261111232529.407154-1-andrew.luebke@gmail.com>

This reverts commit 7556419180a3 ("EDAC/i5000: Mark as BROKEN").

The driver was marked BROKEN, instead of taking the slot loop fix,
because nobody had the hardware to check it with single- and dual-ranked
DIMMs [1]. With the previous patch it loads on an HP xw8400 (5000X) with
all eight slots populated, reports single- and dual-ranked FB-DIMMs with
the right size at the right branch, channel and slot, and stays clean
under KASAN and UBSAN bounds checking.

Two-channel boards (5000V/5000Z) and error reporting are not tested.
