It is strange. I tested the patch on a BT HomeHub 5a and I'm not able to see such an fallout.

Similar curious is, that your wireless seem to have an issue as well:


[    8.838531] ifx_pcie_wait_phy_link_up timeout
[    9.064161] ifx_pcie_wait_phy_link_up timeout
[    9.290225] ifx_pcie_wait_phy_link_up timeout
[    9.516112] ifx_pcie_wait_phy_link_up timeout
[    9.742178] ifx_pcie_wait_phy_link_up timeout
[    9.745108] pcie_rc_initialize link up failed!!!!!


If it only occurs when the patch is applied, there is no way I can associate it with the content of the patch.

However, the failing PCIe might prevent the successful load/initialization of the switch driver.

Would you mind to try to disable the PCIe temporary by applying the following changes on top of 7362sl.patch:
