linux-toradex.git/drivers/net/via-velocity.h, branch v3.0.77 Linux kernel for Apalis and Colibri modules via-velocity: don't annotate MAC registers as packed 2011-05-25T21:55:32+00:00 Ulrich Hecht uli@suse.de 2011-05-25T01:07:22+00:00 d10358de8d70aaeb965a974d56e9b72f6c6dbb3a On ARM, memory accesses through packed pointers behave in unexpected ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163 for discussion. In this particular case, 32-bit I/O registers are accessed bytewise, causing incorrect setting of the DMA address registers which in turn leads to an error interrupt storm that brings the system to a halt.

On ARM, memory accesses through packed pointers behave in unexpected
ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163
for discussion.

In this particular case, 32-bit I/O registers are accessed bytewise,
causing incorrect setting of the DMA address registers which in turn
leads to an error interrupt storm that brings the system to a halt.

Since the mac_regs structure does not need any packing anyway, this patch
simply removes the attribute to fix the issue.
