I am using Intel C3508's built-in 10GbE LAN controller with "1GBASE-T (via Marvell 1543), 1 GbE SKU" (PCI device id 0x15e5), but it fails in rare cases with the probe of ixgbe driver of Linux.
Please tell us if you know the reason why this failure occurs.
The operating system is Linux-4.14.125, using the ixgbe driver of the kernel.
The function of the ixgbe driver that caused an error is ixgbe_reset_hw_X550em().
After performing a link reset by writing 1 to LRST bit (bit 3) of Device Control Register, it seems that LRST bit does not return to 0.
When I displayed the variable ctrl that read the value of Device Control Register when an error occurred, it was 0xdeadbeef.
Is there any way to prevent the device control register value from becoming 0xdeadbeef after reset?
Should I extend the sleep time after reset or read more device control registers?

Since there was a reply that it is possible to post to EmbeddedIntelAtom® forum, I posted the same sentence.
Should posts on intel ethernet be deleted?
