Description Alex Schultz 2005-03-14 19:16:04 UTC

Description of problem:
Below is the chunk of log from dmesg about the stack trace.  When this occurs you cannot log into to the machine via ssh and the console is locked up (we believe it locks up the tty access).

We're running dell 7250 itaniums with qlogic QLA2450-E-SP fibre cards and intel e1000 network cards.  These machines are running oracle 10g and talking to EMC for raw disk access.
