Summary: Interrupt controller hangs on XEON processors
Product: eCos
Version: 2.0
Platform: pc (i386 PC target)
OS/Version: HostOS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: normal
Component: Other
AssignedTo: jifl@ecoscentric.com
ReportedBy: Kevin_Lemay@agilent.com
QAContact: ecos-bugs@sources.redhat.com
After successfully porting my driver to eCos on a 700MZ pentium 3, I attempted
to run it on a newer XEON 2.4GZ to collect performance metrics.
The XEON system consistently hung. Using the debugger, I was able to verify that
enabling the interrupt for the HBA was the trigger for the system hang.
When I modified the driver to poll the hardware (no hardware interrupts), it
runs on the XEON.
There appears to be an incompatibility between the i386 BSP and the newer XEON
processors.
Target platform:
Supermicro P4D-PL-M
Single 2.4 Ghz XEON
(hyperthreading disabled)
