Subject: 2.6.24-rc1 fails with lockup and BUG:


Hi,

2.6.23-rc1 fails for me. I have the sensation it is network-related, but
I am not sure, so I send this message just to the list. 
This same failure was present in git-5734-gd85714d, I sent
a message to the list but it seems it never arrived. I hope this will
pass through. My system is a toshiba satellite A305-S5077, dual core pentium.

The symptoms are quite strange. At boot, NetworkManager fails to activate
my eth0 (r8169). Just stopping/restarting NM will make it works.

Then, after one or two or maximum three suspend to ram and resume that
works, all go awry. Notice that I do not know if the s2ram is the cause, or
simply the way to accelerate the bug.

The suspend-to-ram will fail with a messages: 

"gnome-power-manager: (romano) DBUS timed out, but recovering"

and a number of processes go into D state (please find their sysrq-t traces
few lines down). Now I cannot create new windows, nor doing sudo (sudo
anything will go into D limbo), and not even a clean shutdown. Trying that
the system loops forever saying: 

BUG: soft lockup - CPU#0 stuck for 11s! [ifconfig: 7481]

and sysrq-b is the only option. 

Complete dmesg, config, etc at:
http://www.dea.icai.upcomillas.es/romano/linux/info/2624rc1_1/

Thanks, 

	Romano 

PS sorry for the disclaimer, I cannot stop it (¡!)
