From: Izumi Tsutsui <>
Subject: PR/42516 CVS commit: src/sys/arch/sparc/sparc
Date: Wed, 13 Jan 2010 12:43:06 +0000

 Module Name:   src
 Committed By:  tsutsui
 Date:          Wed Jan 13 12:43:06 UTC 2010
 Modified Files:
        src/sys/arch/sparc/sparc: auxreg.h
 Log Message:
 Explicitly clear AUXIO4M_FTC bit in FTC_FLIP macro used on
 pseudo-dma for floppy, as well as AUXIO4C_FTC bit for sun4c.
 A comment in the macro says AUXIO4M_FTC bit is auto-clear,
 but my two SS20s (including compatible) with 150MHz hyperSPARCs
 get data_overrun without it, and no bad side effect on SS5
 (works with and without this change).
 Closes PR port-sparc/42516, which is the last one of a bunch of
 floppy issue on NetBSD/sparc since NetBSD 2.0 days. See
 for details.
