Description of problem:
When cannaserver is run, errors of this form appear.  

cannaserver(6612): unaligned access to 0x600000000001bc94, ip=0x4000000000026d20

Seems bad to me.

The hardware this was discovered on is an LP-Madison booted from a SmartArray.

Canna-3.6-15

How reproducible:
Always

Steps to Reproduce:
1. run cannaserver

    

Actual Results:  program produced several unaligned access errors as above

Expected Results:  program should run error-free

What were you doing this appeared? I just ran the cannaserver with -d option to
debug it on gdb, but I couldn't see any error messages.
Comment 2 Glen A. Foster 2003-08-13 11:10:47 EDT
It happens in the start-up of HP rx2600 (Longs Peak) and rx5670 (Everest)
servers all the time.  All you need is to boot one, but if you're in Japan,
you'll need to get someone in Raleigh to do this for you... and you might need
to get someone to help with debugging it remotely.
Comment 3 Akira TAGOH 2003-10-14 02:55:09 EDT
FYI: I have tracked it down and fixed it locally. it will be available as an errata.
Comment 4 Glen A. Foster 2003-10-14 13:24:27 EDT
Can this please be included in the BASE RELEASE of RHEL3???
Comment 5 Akira TAGOH 2003-10-15 03:18:44 EDT
Unfortunately no, because of the release schedule. I apologize for not fixing
this earlier.
Comment 6 Glen A. Foster 2004-01-25 19:26:52 EST
This is fixed in RHEL3 update 1
Comment 7 Liudvikas Bukys 2004-05-21 14:52:24 EDT
Did this fix actually make it into IA64 distros?
My Canna RPMs from RHEL 3WS IA64 are -3.6-20,
and neither up2date nor downloaded ISOs of RHEL3 update 2
contain anything different.
