Yes, it works. The suggested one line change did work and fixed the issue for me. I didn't have time to ask for it to be merged.

I'm busy with a lot of other things but I am well aware of this issue. You can silence the noise with "dmesg -n1". Otherwise, it would be greatly appreciated if you could work on a patch to fix this issue. Adrian -- .''`.

dbus-daemon unaligned accesses
On my alpha, the system logs are getting spammed with unaligned trap errors as follows: [34656.586748] dbus-daemon(700): unaligned trap at 020a9720: d68c7222 28 18 [34656.599443] dbus-daemon(700): unaligned trap at 020a9720: d68c7222 28 18 [34656.612138] dbus-daemon(700): unaligned trap at 020a9720: d68c7222 28 18 [34656.617021] dbus-daemon(700): unaligned trap at 020a9720: d68c7222 28 18 [34656.624833] dbus-daemon(700): unaligned trap at 020a9720: d68c7222 28 18 The current "dbus" package version is 1.12.16-2. If no one else is actively working to fix this annoyance, I'll see what I can do. For me, it's mostly a matter of finding the time to download the source package and its dependencies, build a debug version with symbols in it that "gdb" can use, and then *maybe* figure out the best way to code around the unaligned access. If anyone else has the time and would like to have a go at it, the following two links might be useful: https://wiki.gentoo.org/wiki/Project:Alpha/Porting_guide#Unaligned_accesses https://www.redhat.com/archives/axp-list/2000-May/msg00151.html (Yes, the problem has been around at least as long as the alpha architecture :-) ). Michael Cree et al.: do we have a working "gdb" on alpha these days? I seem to recall brokenness there in the not-too-distant past. --Bob
