Subject: [PATCH] usb-storage: Add US_FL_IGNORE_UAS for JMicron JMS581
Date: Sat, 1 Aug 2026 11:47:51 +0100 [thread overview]
Message-ID: <20260801104751.277572-1-chris.bainbridge@gmail.com> (raw)
Enabling UAS results in a 30-second boot hang when using a JMicron
JMS581 NVMe enclosure (specifically SSK 'SHE-C325 PRO' with a WD PC
SN520 NVMe drive).
Fixes:
