Bug ID: 215029
Summary: Clean unregistration of SMSC9500 chip at halting
system failed
Product: Networking
Version: 2.5
Kernel Version: 5.15.1
Hardware: ARM
OS: Linux

Hi,
after switching from kernel version 5.10.65 to 5.15.1 I recognized a failing
unregistration of the SMSC9500A chip during shut down the system.
We build the kernel and all other needed stuff from scratch for an i.MX6Q
module (armv7l) provided by TQ-Systems GmbH for our own base-board. For this we
are using ptxdist as environment/building tool together with the
OSELAS-Toolchain as cross-compiler.
Since kernel 3.16 we had now issue like that...
Because we just upgrade from LTS to LTS versions, I can only say that the issue
till kernel 5.10.65 does not exist.
Following kernel-messages show the issue with kernel 5.15.1:

Although we had on our base-board just a SMSC9500A chip there will be mentioned
a "SMSC LAN8710/LAN8720" during establishing a network connection on this port.
If I compare drivers/net/phy/smsc.c for 5.10.65 and 5.15.1 then there were made
some changes - I think of the note:
/* This covers internal PHY (phy_id: 0x0007C0F0) for
* LAN9500A (PID: 0x9E00), LAN9505A (PID: 0x9E01)
*/
Please ask if you need some further details to understand/solve this issue.
Thanks in advance.

Hi,
after switching from kernel version 5.10.65 to 5.15.1 I recognized a failing
unregistration of the SMSC9500A chip during shut down the system.
We build the kernel and all other needed stuff from scratch for an i.MX6Q
module (armv7l) provided by TQ-Systems GmbH for our own base-board. For this we
are using ptxdist as environment/building tool together with the
OSELAS-Toolchain as cross-compiler.
Since kernel 3.16 we had now issue like that...
Because we just upgrade from LTS to LTS versions, I can only say that the issue
till kernel 5.10.65 does not exist.
Following kernel-messages show the issue with kernel 5.15.1:

Although we had on our base-board just a SMSC9500A chip there will be mentioned
a "SMSC LAN8710/LAN8720" during establishing a network connection on this port.
If I compare drivers/net/phy/smsc.c for 5.10.65 and 5.15.1 then there were made
some changes - I think of the note:
/* This covers internal PHY (phy_id: 0x0007C0F0) for
* LAN9500A (PID: 0x9E00), LAN9505A (PID: 0x9E01)
*/
Please ask if you need some further details to understand/solve this issue.
Thanks in advance.
