Red Hat Bugzilla – Bug 39708
System becomes unresponsive under load
Last modified: 2005-10-31 17:00:50 EST
Description of Problem:
When running heavy filesystem the RedHat systems become unresponsive &
must be power cycled. All I/O also stops. When setting swiotlb=16384 the
system will virtually stop after only several minutes. Increasing the
value to 32k allows the system to run somewhat longer.
Controller under test: ROC
Compaq IA64 system Pilot-4
Latest ida (2.4.4) & cciss (2.4.5) drivers
Steps to Reproduce:
Which kernel is this exactly ?
closing, lack of input.
Hardware changes. This is fixed
