[21:57] <a7x> hi, just installed a new nvme device on two different PCs (same drive model, same pc model), one of them was much slower than the other and after a few hours of test I noticed the following information spammed in dmesg " nvme nvme0: I/O 284 (I/O Cmd) QID 4 timeout, aborting" "nvme nvme0: I/O 284 QID 4 timeout, reset controller" "nvme nvme0: 8/0/0 default/read/poll queues"
[21:58] <a7x> I tried setting default_ps_max_latency_us to 0 (cat /sys/module/nvme_core/parameters/default_ps_max_latency_us
[21:58] <a7x> 0
[21:58] <a7x>  -> 0) but this didn't fix the issue
[21:59] <a7x> well, the fun thing is that I did the same change on both PCs and now both of them show the same dmesg error
[22:29] <tomreyn> a7x: which device is it? have you looked for firmware updates for the nvme? have you looked for firmware updates for the mainboards? are both computers the same? which pci lanes have you connected them to (the same, if same board)?
[22:29] <tomreyn> also which ubuntu version and kernel version are you using.
[22:37] <a7x> the device is an nvme with phison controller, I am going to look for updates. There is an update for the system I will do it now. Both PC are identical, there is only 1 nvme m2 slot. Kernel: h6.2.0-39-generic, Ubuntu 23.04
[22:41] <a7x> according to the producer websites there are no updates, but the only way to be certain is to install their proprietary software on Windows
