When the system is locked I am able to ping it, to use sysrq-key, even more, I can try to login into the console, or debug-console, but login hung after I enter 'root' and hit the enter. When there is open remote ssh session at hung am able to run a few commands until one of them (probably) ask VFS. At hung, when I use sys-rq to Crash or show CPU trace there are evidences that one of my CPUs is idle, and the second is printing out the trace. I am tried to hung softlock, using kernel.softlockup_panic, and I found that there are no softlocks. After experimenting with kernel.hung_task_warnings I found that all of my system processes are blocked. Unfortunately, I was not able to log hung traces in digital format, only as screen shots made by my mobile phone. Attached here are 8 shots of the hung warnings. My root filesystem is mounted as: /dev/disk/by-id/md-name-2 / reiserfs acl,user_xattr,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0 1 1 I can't reproduce this on demand, but It happens frequently enough to try collect some additional data, if needed. When I disable quota in my system, I am PRESUMABLE not able to reproduce the issue.
