Hi, We've backported the patch to our kernel, and redo the test[1] that formerly caused system stall. After 12-hours, no system stall observed.
Regards, Chen Jie
---- [1] The test is just do "sleep 5 && reboot " on our mips64 compatible CPU@500MHz. At each boot time, BIOS will calculate CPU Freq. Some CPU Freq(around 500MHz) caused easy-overflow clock mult values in the former tests, which then led to "sleep 5" never return.
