The issue seems to be resolved after kernel upgrade to 5.10.0-1049-oem
I got an XPS 15 (9500) recently. It has an SD card slot, so I decided to try installing Linux on an SD card. This way, I can test how Linux works on it without having to destroy the existing Windows installation. I tried installing Debian, versions stable and testing. I got the testing because I needed a newer kernel that would support the WiFi adapter, Wi-Fi 6 AX201. 00:14.3 Network controller: Intel Corporation Device 06f0 I tried install it, and I got those messages: Jun 6 18:48:28 kernel: [ 1813.509645) ? ext4_sync_file+oxf2/0x3a0 (ext4)Jun 6 18:48:28 kernel: [ 1813.509649] ? do_fsync+0x38/0x70Jun 6 18:48:28 kernel: [ 1813.509652) ? __X64_sys_fsync+0x10/0x20Jun 6 18:48:28 kernel: [ 1813.509658] ? do_syscall_64+0X52/0x180Jun 6 18:48:28 kernel: [ 1813.509664) ? entry_SYSCALL_64_after_huframe+OX44/0xagJun 6 18:48:57 kernel: [ 1842.296 782) blk_update_request: I/O error, dev momcbiko, sector 115136336 op Ox1: (WRITE) flags Ox800 phys_seg 1 prio class o Jun 6 18:48:57 kernel: [ 1842.296 792) EXT4-fs warning (device mmcblkop2): ext4_end_bio:347: I/O err or 10 writing to inode 6291467 starting block 14392043) Jun 6 18:48:57 kernel: [ 1842.312416) blk_update_request: I/O error, dev mmcblko, sector 11585064 0 p0x1: (WRITE) Flags Oxo phys_seg 2 prio class o Jun 6 18:48:57 kernel: [ 1842.312425) EXT4-fs warning (device mmcblkop2): ext4_end_bio:347: I/O err or 10 writing to inode 6291656 starting block 1448134) Jun 6 18:48:57 kernel: [ 1842.312431) Buffer I/O error on device mmcblkop2, logical block 1316805 Jun 6 18:48:57 kernel: [ 1842.312442) EXT4-fs warning (device mmcblkop2): ext4_end_bio:347: I/O err or 10 writing to inode 6291656 starting block 1448135) Jun 6 18:48:57 kernel: [ 1842.314543) blk_update_request: I/O error, dev mmcblko, sector 123058984 Op 0x1: (WRITE) flags Ox800 phys_seg 30 prio class o Jun 6 18:48:57 kernel: [ 1842.314615) Buffer 1/0 error on device mmcblkop2, logical block 14260714 Jun 6 18:48:57 kernel: [ 1842.314623) Aborting journal on device mmcblkop2-8.

Fun!) Maybe the SD card is bad? I tested the SD card in another computer, with a destructive read/write test. No bad blocks. Maybe this SD adapter doesn't like this SD card? I tried to install Debian XPS 15 on another SD card. Errors. Maybe the SD adapter is busted? I formatted the SD card on Windows on XPS 15 and ran a full disk check, with chkdsk with option /r. No bad blocks. I installed Debian on XPS 15 on the SD card, using an external SD-to-USB adapter. No errors. So, to reproduce the problem I need two things: Linux and the internal SD slot. Did anyone else run into this? Any ideas how to proceed?
