Bed Thermal Runaway - Time to reach 100°C?

Yesterday while printing an ABS object I got the "BED THERMAL RUNAWAY" error. It took about 20 mins for the bed to reach 100°C, but my IR temperature reader was reading about 110°C. When it started printing, the temperature dropped to 96 and that's when I got the error. It happened twice. I printed ABS before and it was fine (i upgraded to Firmware 3.0.11 a few days ago).

I visually checked the bed thermistor which seems to be well attached to the bottom, and I use a printing chamber.

My question to you guys is:

How long does it take for your Prusa MK2 to reach 100°C?

P.S. I know there are quite a few "Bed Thermal Runaway" references in the forum, but I haven't had this problem before upgrading to Firmware 3.0.11. There might be an issue there?
