Thread: System stops in random intervalls ...


hi all,

i've got serious problem ubuntu 11.10 running on dell optiplex 990 machine.
whatever do, system randomly stops. imagine working on shell , randomly you
won't prompt. or while typing system stops , won't return prompt if ctrl+c'ed.

got hardware tested. everythings fine. memory, system (bios , on, dell has pre-check-tool), harddisk (smartctl health tests pass , on) , network (fine!) ...
, problems remains if have no gui , pure shell.

system clock seems stop randomly, kernelparameters noapic, nolapic doesn't help.

although network finely working, when ping machine you've got package loss of 20%, caused system stop randomly. (e.g. 20 pings out, 10 pings missing, 10 pings out, 40 pings missing)

magic sysrq key seems work, not make out of messages.

don't know check now. maybe you've got suggestions ...
i'd appreciate hints.

did system log files after stops? machine getting hot?
