2011-04-29 Thread David McGiven
Sorry, I'm still having the same problem with Ubuntu 10.04.2, either
using :

2.6.32-30.59
or
2.6.35-020635rc1

What should I do to fix this problem ?

Thanks.

2011-04-29 Thread David McGiven
Dear All,

I'm having this issue as well but I don't understand what is the
proposed solution. Where is that 2.6.35.something kernel that fixes the
problem ?

Please help!

I can see the bug with those two kernels :
2.6.35-020635rc1
2.6.32-30.59

Thanks

It's very sad that this bug is not being fixed by Ubuntu developers. I'm
very disappointed.

[Bug 556350] Re: BUG: soft lockup - CPU#0 stuck for 61s! [events/0:6]

2010-05-26 Thread David McGiven
Charlie,

I have the same problem as the user who posted the bug, although I'm
using 8.04 LTS with kernel 2.6.24-27.

It's a very annoying bug because you don't really know if it's because a
bug in the kernel or a hardware failure. Both options sound possible to
me ...

Do you want me to post some more information ?

Thanks

Well, I've added the noapic boot option and now I am not able to
reproduce the error ...

That's an step forward ...

2010-05-26 Thread David McGiven
Dear Ubuntu Users,

I'm hitting the same error/bug you are. My setup is the following :

- SunFire X4450 with 4 Intel Xeon 6-Core :
(Intel(R) Xeon(R) CPU   E7450  @ 2.40GHz)

- Ubuntu 8.04 LTS :
No LSB modules are available.
Distributor ID: Ubuntu
Description:Ubuntu 8.04.4 LTS
Release:8.04
Codename:   hardy

- Kernel version :
Linux x 2.6.24-27-server #1 SMP Wed Mar 24 11:32:39 UTC 2010 x86_64 
GNU/Linux

- I'm running a 24 processors NAMD job
(http://www.ks.uiuc.edu/Research/namd/)

After less than 1 minute, the system becomes unresponsive for ~10
minutes and then it comes back to "normal" (no need to reboot if you are
patient enough).

Checking the dmesg buffer shows the already discussed "[ 2618.201092]
BUG: soft lockup - CPU#23 stuck for 11s! [events/23:98]"

I've also seen some messages regarding a RAID module :
[ 2625.160886] aacraid: Host adapter abort request (0,0,0,0)
[ 2625.161029] aacraid: Host adapter reset request. SCSI hang ?

But I don't know if they're very relevant because the software and the
data are accessed through NFS so it's not really writing to a local
disk.

Does this provide any help to solve the problem ? I can send more
detailed logs to the ubuntu LTS team if needed, this bug has to be
solved! it's been more than a year now.
