From 6f52e69f468f3b75db0292be3ee479db699a9a57 Mon Sep 17 00:00:00 2001 From: John Snow Date: Fri, 24 Jul 2020 01:22:59 -0400 Subject: ide: clear interrupt on command write Not known to fix any bug, but I couldn't help but notice that ATA specifies that writing to this register should clear an interrupt. ATA7: Section 5.3.3 (Command register - Effect) ATA6: Section 7.4.4 (Command register - Effect) ATA5: Section 7.4.4 (Command register - Effect) ATA4: Section 7.4.4 (Command register - Effect) ATA3: Section 5.2.2 (Command register) Other editions: try searching for the phrase "Writing this register".
