Key facts

Description

In the Linux kernel, the following vulnerability has been resolved: arm64: dts: imx8mm-verdin: Do not power down eth-phy Currently if suspending using either freeze or memory state, the fec driver tries to power down the phy which leads to crash of the kernel and non-responsible kernel with the following call trace: [ 24.839889 ] Call trace: [ 24.839892 ] phy_error+0x18/0x60 [ 24.839898 ] kszphy_handle_interrupt+0x6c/0x80 [ 24.839903 ] phy_interrupt+0x20/0x2c [ 24.839909 ] irq_thread_fn+0x30/0xa0 [ 24.839919 ] irq_thread+0x178/0x2c0 [ 24.839925 ] kthread+0x154/0x160 [ 24.839932 ] ret_from_fork+0x10/0x20 Since there is currently no functionality in the phy subsystem to power down phys let's just disable the feature of powering-down the ethernet phy.
