SubjectRegression with v5.18-rc1 tag on STM32F7 and STM32H7 based boards
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
