the subpages test fails with:
[ 82.435792] mtd_subpagetest: written up to eraseblock 7424
[ 82.905775] mtd_subpagetest: written up to eraseblock 7680
[ 83.375201] mtd_subpagetest: written up to eraseblock 7936
[ 83.840447] mtd_subpagetest: written 8192 eraseblocks
[ 83.845522] mtd_subpagetest: verifying all eraseblocks
[ 83.852740] uncorrectable error :
[ 83.856086] mtd_subpagetest: error: read failed at 0x0
[ 83.861469] mtd_subpagetest: error -74 occurred
[ 83.866093] =================================================
Error: could not insert module ./drivers/mtd/tests/mtd_subpagetest.ko: Bad message
I don't have a clue yet how to debug that further. Will start with
checking older kernel releases. Any hints welcome.
Best regards
Uwe
