[parisc-linux] tst unaligned access

[Martin Küchler]

Hello,

After a successful uptime of about a month, I could not log in to my 712/60 
any longer. I found the following error message at the console: 

tst(11624): unaligned access to 0xbff003d4 at ip=0x000105b3
Not-handled unaligned insn 0x2f401016
unaligned handler failed, ret = -1

I am not even sure if this is the cause of the login problem, but I found a 
description that was samewhat similar (but on a different machine):

http://lists.debian.org/debian-hppa/2001/debian-hppa-200109/msg00053.html

My problem was, everything was working fine (network, iptables with 
masquerading, server processes ...), but when I tried to log in he just 
wouldn't give me the shell (after the username/password I got the login 
message and nothing else). 

Even shutdown with the soft power switch didn't work, I had to pull the plug 
:-(
But now, after reboot everything seems to be fine ... 

What could this have been ? And what is this tst process ??

I have a 2.4.18-pa22 kernel,  iptables v1.2.6a.

Thanks,

Martin

that's fldd 0(sr0,r26),fr22 (thanks Richard!)... the unaligned handler
doesn't do floating point insns at the moment.

try a newer kernel? there were some hanging process problems that were
fixed recently, though i think there are some other ones still there...

i have no idea what tst is though....

Hi Martin,

FYI, I had similiar problems on a 715/50 in the past. It hung sometimes after one week
of uptime and it seemed to me as if the SCSI driver was unable to access the disc
and thus didn't gave me a login prompt or anything else.
After upgrading the kernel to the most recent one (>= 2.4.18-pa35) which has some
IRQ fixes in it , and which seems to cure the SCSI driver problems, the box now seems 
to work stable.
In case you update your kernel, could you please let us know if the box works stable for 
you too ?

Greetings,
Helge
