Description of problem: we got BUG messages in the system log file /var/log/messages. All running processes seems to work well. at fist a sh login was possible. commands such ps, top hangs and did not come back. ping also works well. after some tries to monitor the system, no more sh login was possible. a reboot hangs also. we can only start a cold reset. please see above the messages and dmesg log file of the server. How reproducible: sometimes, but not always. Steps to Reproduce: 'ps axuwwww' or 'top' Actual results: the command did not come back, if the system was in this status and the BUG occoured the first time. some commands such 'ls', 'df' works well. Expected results: output of the process list, or status of the system per 'top' Additional info: excerpt from /var/log/messages: Dec 15 23:15:44 ssps01 kernel: ------------[ cut here ]------------ Dec 15 23:15:44 ssps01 kernel: kernel BUG at highmem.c:145!
