Re: e1000 driver intel 82574L non-responsive and high ping times
Hi Hugh,
I ended up finding a solution, using apic_startup and pci-bios-v2 by
building the qnxbasesmp-apic.build image and booting from that. I also
reverted to the original 6.5 e1000 driver.
For information I have included the system information in apic_boot.zip
when both nics are working correctly.
Also I have attached logs for the test driver you sent me. These were
captured when using pci-bios, with the issue visible.
Many thanks for your help.
Regards,
Elisha
