NVMe timeout when booting from eMMC but not SD

[alexeymin]

I'm seeing the same 60s delay and the same timeout with the same SSD (Kingston A2000 256 Gb) when booting from eMMC:

Code:

[   1.886899] usb 2-1.2: Manufacturer: Sonix Technology Co., Ltd.
[  31.847180] vbus_5vout: disabling
[  64.487248] nvme nvme0: I/O 0 QID 0 timeout, disable controller
[  64.607160] nvme nvme0: Device shutdown incomplete; abort shutdown
[  64.608409] nvme nvme0: Identify Controller failed (-4)
[  64.609050] nvme nvme0: Removing after probe failure status: -5
[  64.640311] Freeing unused kernel memory: 2816K
[  64.707554] Run /init as init process

P.S. I'm using posmarketOS

What's interesting though is that u-boot seems to recognize the drive fine during boot: https://imgur.com/q59Hiel



Also when booting the same posmarketOS image (or Manjaro ARM image) from SD card there are no timeouts and it can see this nvme drive just fine.

Instructions to alter kernel cmdline from this post from kernel bug report - https://bugzilla.kernel.org/show_bug.cgi?id=195039#c73 - specifically 

Code:

nvme_core.default_ps_max_latency_us=0 pci_aspm=performance

also don't help

That kernel bug report also mentions kingston firmware update that might help - https://www.kingston.com/unitedstates/us...are-update - that you can only install from Windows

Code:

Firmware Rev S5Z42109(03-30-2021):
Fixed an issue that might cause the drive to become unresponsive on Linux systems

If nothing works I guess I'll try another SSD
