Could you modify this to print the full values of cwd and swd like this?
printk("MATH ERROR: cwd = 0x%hx, swd = 0x%hx\n", cwd, swd);
Then post the result.
MATH ERROR: cwd = 0x37f, swd = 0x5020
MATH ERROR: cwd = 0x37f, swd = 0x20
MATH ERROR: cwd = 0x37f, swd = 0x20
MATH ERROR: cwd = 0x37f, swd = 0x2020
MATH ERROR: cwd = 0x37f, swd = 0x20
MATH ERROR: cwd = 0x37f, swd = 0x1820
MATH ERROR: cwd = 0x37f, swd = 0x1820
MATH ERROR: cwd = 0x37f, swd = 0x2020
MATH ERROR: cwd = 0x37f, swd = 0x20
MATH ERROR: cwd = 0x37f, swd = 0x2800
MATH ERROR: cwd = 0x37f, swd = 0x1820
MATH ERROR: cwd = 0x37f, swd = 0x820
MATH ERROR: cwd = 0x37f, swd = 0x2820
MATH ERROR: cwd = 0x37f, swd = 0x2820
MATH ERROR: cwd = 0x37f, swd = 0x1820
MATH ERROR: cwd = 0x37f, swd = 0x820
MATH ERROR: cwd = 0x37f, swd = 0x1a20
