Public bug reported:
I looked at similar bugs, but the characteristic of those kind of issues
being limited information, I couldn't be sure that my case was exactly
the same as an other, so I opened a new bug. Typically, those kind of
hangs are very hard to diagnose because of the lack of logging. (See
further on how I got more info)
So, what happens is that my IBM Lenovo Thinkpad x60s totally locks frozen after
some time on a daily basis. Even during the night under light load. Higher
network load seems to make it hang faster, especially when it acts as a router
and traffic transitions through it to an other machine on the internal network.
(I was running Windows XP before that and I never had any problems of this
kind) At this point, I can say that the problem is reproducible daily. I am
lucky that my file system didn't get corrupted yet with all the daily hangs ...
I hope it will not happen as I type this bug report.
Technical information:
Ubuntu 8.04.1 Hardy
uname -a
Linux travel 2.6.24-19-generic #1 SMP Fri Jul 11 23:41:49 UTC 2008 i686
GNU/Linux
cat /proc/cmdline
root=/dev/mapper/travel-root ro console=ttyS0,115200n8 console=tty0
"Visual Effects" disabled.
I use an encrypted file system. (Installed from alternate CD)
I use shorewall for my firewall rules.
I installed the linux-backports-modules-hardy package for the latest
iwl3945.
I also use an external monitor with 1600x1200 resolution. (See X log
file for more info)
The x60s sits on its docking station. All cables run from it.
The BIOS is the latest. (v2.17, see dmidecode output)
I didn't perform a suspend-resume cycle before the machine hang.
I use 2.6.24-19-generic and couldn't test with 2.6.24-20-generic because
my system doesn't boot with it. (The subject of an other coming bug
report)
Being tired of those freezes every days with no error message written to
the disk, I finally got the time to purchase a null modem cable,
connected from the docking station to an other laptop running minicom,
enabled printk capture at boot and I got the following lines printed at
the point of freeze:
[25408.657345] Uhhuh. NMI received for unknown reason a1 on CPU 0.
[25408.663266] You have some hardware problem, likely on the PCI bus.
[25408.669440] Dazed and confused, but trying to continue
Other than that, the information files are attached in a tar archive:
dmesg.log
lspci-vvnn.log
lspci-vv.log
xorg.conf
dpkg-l.log
lsmod.log
proc-interrupts.log
Xorg.0.log
dmidecode.log
smartctl_--all_-d_ata_dev+sda.log
sysctl-a.log
cpuinfo.log
Hope it helps.
