Booting v7.1-rc4 hangs on a single core CPU, bisected to ff1c0c5d07028

Hi,

booting Linux 7.1-rc4 on my Allwinner D1 (single core RISC-V) board
hangs during boot.
The last messages are MMC related, but further testing revealed that
the system hangs at  msleep()/usleep_range() calls.

I did an assisted bisect which points to this merge commit:
ff1c0c5d07028 Merge branch 'timers/urgent' into timers/core

I tried the suggested workaround "revert clockevents.c to the version
from 09c04714cb455" and it fixed the problem for me.

Can anyone with a single-core (RISC-V?) system confirm this? It seems
to be no issue on SMP.

Best regards,
Indrek
