Hi!
With my currently installed ping (netkit-ping 0.10-6 from Debian Woody)
I get unaligned accesses:
ping(15953): unaligned trap at 00000001200030e4: 0000000120026b34 29 1
ping(15953): unaligned trap at 0000000120003110: 0000000120026b2c 29 2
The worse part is: they seem to be handled The Wrong Way:
[jbglaw@air:/home/jbglaw] $> ping -c 1 localhost

This is on a NoName Alpha box, running 2.4.0-test8-pre1 (with very good
uptimes), but I think 2.4.2-pre2 would do the same (wrong) things as
arch/alpha/kernel/traps.c wasn't really changed since ages... I don't
know much about alpha assemlbly language so somebody else should have
a look at that;( Btw., when such an unaligned trap has happened, I also
get transmit timeouts on my network card (which is:
00:0c.0 Ethernet controller: 3Com Corporation 3c905 100BaseTX [Boomerang]
NETDEV WATCHDOG: eth0: transmit timed out
eth0: transmit timed out, tx_status 00 status e000.
Flags; bus-master 1, full 1; dirty 1470429(13) current 1470445(13).
Transmit list 477a42d0 vs. fffffc00077a42d0.
0: @fffffc00077a4200 length 80000042 status 00000042
