Hi Manuel, I may have reported the same problem in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=221227 Can you try adding the following lines to GENERIC-NODEBUG: nodevice ds1307 # Dallas DS1307 RTC and compatible nodevice ds133x # Dallas DS1337, DS1338 and DS1339 RTC nodevice ds1672 # Dallas DS1672 RTC nodevice ds3231 # Dallas DS3231 RTC + temperature nodevice nxprtc # NXP RTCs: PCA/PFC212x PCA/PCF85xx nodevice s35390a # Seiko Instruments S-35390A RTC I have a suspicion one of these devices is making the kernel panic. It solved my bug. Cheers, Sylvain.
