Facing a similar issue like this. A similar error pops up, after which, all the attached devices get disconnected and gets back connected after a couple of seconds.

Please help me get an idea about what this error means and what might be the cause of it.

same problem and I think my pi is dying. Cause it also reboots itself regularly.

Reboots are very often caused by inadequate power supply or power supply cable. I'd be very surprised if it's due to the pi dying.

For the source of the original error message, there is a not-well-understood behaviour of the dwc2 hardware where it encounters an error condition and the root port enters the disconnected state, but doesn't signal a disconnect interrupt for some time. During this window, all active host channels report halt conditions without any other interrupt bits set. The host channel that's going into a halt state should specify the reason for halting, which is why the FSM complains.

The prime candidate has always been unstable power, but the exact conditions to cause just this issue (without e.g. rebooting the Pi or causing SD card errors) have never been found out.

External USB 3.0 hubs, and I generally see this after 2-4 days. This is the last message before the PI in question (with an NFS Boot) halts. WARN::dwc_otg_hcd_handle_hc_fsm:2462: Unexpected IRQ state on FSM transaction:dev_addr=6 ep=1 fsm=6, hcint=0x00000002
