Hi Guys We found an issue with last kernel tag v5.18-rc1 on stm32f746-disco and stm32h743-disco boards (ARMV7-M SoCs). Kernel hangs when executing SetPageUptodate(ZERO_PAGE(0)); in mm/filemap.c. By reverting commit 56a8c8eb1eaf ("tmpfs: do not allocate pages on read"), kernel boots without any issue. Thanks Patrice
