Redhat disabling network interface - IRQ issue
Hi.

I'm having problems on multiple Red Hat VM's (on esxi) whereby the network interface IRQ is disabled by the OS. This is the error from dmesg:

Code:
        command: Write(10): 2a 00 03 42 3f e0 00 00 08 00
mptscsih: ioc0: task abort: SUCCESS (sc=ffff81018b45c680)
irq 67: nobody cared (try booting with the "irqpoll" option)

Disabling IRQ #67

and the interrupts file shows IRQ 67 as eth0.:

Code:

LOC: 4198621982 4198586609

MIS:          0

Any ideas how I can troubleshoot this? We experienced a network outage today, and once it came back, we noticed that the NICS on around 5-6 RH VM's had been disabled with exactly the same errors given above. Red Hat v5.5, ESXi v 4.

Any ideas on how to troubleshoot this would be much appreciated.

gledgeflag

GLEDGEFLAG(3G)															    GLEDGEFLAG(3G)

NAME

       glEdgeFlag, glEdgeFlagv - flag edges as either boundary or nonboundary

C SPECIFICATION

       void glEdgeFlag( GLboolean flag )

PARAMETERS

       flag  Specifies the current edge flag value, either GL_TRUE or GL_FALSE. The initial value is GL_TRUE.

C SPECIFICATION

       void glEdgeFlagv( const GLboolean *flag )

PARAMETERS

       flag   Specifies a pointer to an array that contains a single boolean element, which replaces the current edge flag value.

DESCRIPTION

       Each  vertex  of  a  polygon, separate triangle, or separate quadrilateral specified between a glBegin/glEnd pair is marked as the start of
       either a boundary or nonboundary edge.  If the current edge flag is true when the vertex is specified, the vertex is marked as the start of
       a boundary edge.  Otherwise, the vertex is marked as the start of a nonboundary edge.  glEdgeFlag sets the edge flag bit to GL_TRUE if flag
       is GL_TRUE, and to GL_FALSE otherwise.

       The vertices of connected triangles and connected quadrilaterals are always marked as boundary, regardless of the value of the edge flag.

       Boundary and nonboundary edge flags on vertices are significant only if GL_POLYGON_MODE is set to GL_POINT or GL_LINE.  See glPolygonMode.

NOTES

       The current edge flag can be updated at any time.  In particular, glEdgeFlag can be called between a call to glBegin and the  corresponding
       call to glEnd.

ASSOCIATED GETS

       glGet with argument GL_EDGE_FLAG
