What I mean specifically is that the kernel dated October 7 works fine, and
any more recent kernel hangs solidly if I boot it. Obviously, this is
somewhat inconvenient. :-)
The device in question is a PCI-X Neterion 10gbps card. The output from the
kernel when the device driver is loaded is:
Copyright(c) 2002-2005 Neterion Inc.
xge0: <Neterion XframeII 10GbE Adapter, Revision 2, Driver v2.0.0.6765> mem
0xd8300000-0xd8307fff,0xd8400000-0xd84fffff,0xd8308000-0xd83087ff irq 25 at
device 1.0 on pci129
xge0: Device is on 64 bit PCIX(M1) 133MHz bus
If there's more information I can provide I'm happy to do so, just let me know
what's needed.
Is there a way I can disable vpd support at boot-time in some form -- i.e.,
via a tunable? It would be very useful if these machines worked.
