Public bug reported:
My laptop is a Dell XPS 9530 and comes with a Realtek PCI Express SD card
reader.
I'm using a dualboot Win10/Xubuntu setup, but the card reader has been
problematic in Linux ever since a kernel upgrade years ago. To start from a
clean slate, I reinstalled XUbuntu 21.10 from scratch from the live CD.
First I checked within the live environment if the card reader worked and it
did. Only "Eject" gives an error but otherwise everything worked multiple times.
After installing to HD however, nothing happens when inserting a card.
Not even a dmesg entry.
When I run lspci, with the card still inserted, it is suddenly detected and
automounted in Thunar.
In dmesg appears:
[ 268.053725] mmc0: cannot verify signal voltage switch
[ 268.181990] mmc0: new ultra high speed SDR104 SDHC card at address e624
[ 268.244413] mmcblk0: mmc0:e624 SL16G 14.8 GiB
[ 268.262138] mmcblk0:
[ 283.766834] mmcblk0:
lspci gave:
07:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5249 PCI
Express Card Reader (rev 01)
I cannot unmount the card however, and any new attempts to get it
detected by removing and inserting the card, running lspci again, fail.
The disk entry in Thunar is basically stuck until reboot.
