I could compare the lsmod's outputs between kernel 5.12 and 5.13, and here are the results: Only in kernel 5.12: uvcvideo 110592 0 ecc 32768 1 ecdh_generic Only in kernel 5.13: tun 61440 2 bpfilter 16384 0 ofpart 20480 0 cmdlinepart 16384 0 spi_nor 90112 0 mtd 86016 4 spi_nor,cmdlinepart,ofpart pl330 36864 4 asn1_encoder 16384 1 trusted tee 45056 1 trusted By what I could find, none of them seems related to this issue. Would you have any pointers on what to look for next?
