Hi,
I am trying KGDBOE on the following kernel
Kernel - linux-2.6.32.46 (With SMP set)
Hardware - x86 64bit machine (Intel Nehlaum)
Ethernet - E1000 driver is used
But I am getting the following error
........
............

Is KGDBOE supported by upstream? Actually I don't find it
in the source tree.

Only stand for myself
Hi Yong,
Yes, I know they have removed the KGDBOE support. I have forward
ported the patch to linux-2.6.32.46 kernel. I was just trying to
understand this issue belongs to which of the category ?
1. Is there any issue with Ethernet driver E1000 issue ?
2. Is it belongs to KGDB ?
3. Is there any kernel SMP hang issue for x86 64bit architecture which
is fixed in upstream kernel ?
4. None of the above and something else is broken ?
Is there any available patch ? any guidance to fix the error in E1000
driver. I will really appreciate your help.
Thanks and Regards

Maybe you can try with other KGDB method to debug your system, like
KGDB_SERIAL_CONSOLE.
Thus you can narrow down your problem.

Only stand for myself
Hi Yong,
Thank you very much for the suggestion.
Yes, I am able to use other KGDB methods like KGDB over serial,
console..But I want to make it work KGDBOE. Hence I am requesting is
there anybody tried and come across the "Ignoring packet error,
continuing..." error ?
Thanks
