Hi Guenter! > I tried again, this time with v5.5-rc5. Loading and unloading ahci and > drivetemp in any order does not cause any problems for me. I tried your hwmon-next branch and it still happens for me. Both in qemu and on real hw. I'm really low on bandwidth the next couple of days. Will try to look later this week unless you beat me to it. I get lots of these warnings after modprobe drivetemp; modprobe ahci: [ 1055.611922] WARNING: CPU: 3 PID: 3233 at drivers/base/dd.c:519 really_probe+0x436/0x4f0 A quick test forcing synchronous SCSI scanning made no difference. -- Martin K.
