Hi everybody,

After attach a recent purchase of Samsung EVO 512Gb MicroSD Card, it’s detected and works well, but system boot time increase a lot (Laptop Thinkpad T15 Gen1)

$ systemd-analyze blame
52.283s systemd-udev-settle.service
11.379s abrtd.service
10.953s dracut-initqueue.service
10.172s systemd-cryptsetup@luks\x2dfd943b8d\x2d65cb\x2d40dd\x2dabcd\x2d6bd4b874b055.service
 6.273s NetworkManager-wait-online.service
 3.410s plymouth-quit-wait.service

And several boot errors appears in journal:

journalctl -b | grep mmc

Anyone knows how to fix slow boot time and “failed to write ATTR” errors??

Kind regards

I don’t know why it could be and if it is related to the SD card, but this bug report could be related at least to that message:

Bug 2001058 - systemd-udev-settle.service is deprecated. Please fix multipathd.service not to pull it in.

(It contains a possible workaround).
