es it mean we need to slow down acpi_ec_intr_read/write ?

Really strange, how several printks could change the results.
Could you try to repalce acpi_os_stall with acpi_os_sleep(1)

Also, please change I2RB copy to:
Method (I2RBcopy, 3, NotSerialized)
Store (Arg0, HCSL)
Store (ShiftLeft (Arg1, 0x01), HMAD)
Store (Arg2, HMCM)
Store (0x0B, HMPR)
And boot with acpi_dbg_layer=0x10 acpi_dbg_level=0x10,
Post full log (Don't edit) for both not hang case, and hang case on
There should have some clues.
