Hi there,
I'm not sure when it started, but noticed it around 5.12.9 - have to admit though, that I was probably very lazy when doing backups during the last months... Anyway, when plugging a SATA disk into some disk tray, the kernel doesn't detect a new device. This used to work perfectly some months before, and it actually still does on Leap's default kernel (both 15.2 and 15.3). The following kernels both show this bug:
kernel-default-5.12.10-2.1.gb92eaf7.x86_64 kernel-vanilla-5.12.10-2.1.gb92eaf7.x86_64
strange thing, really! Just found the culprit: somehow the "Hot Plug" bit for the SATA port connected to the tray box got disabled in the BIOS. Really don't know how this could have happened, but I guess it must have been during a BIOS update as the misbehaviour could be reproduced on two otherwise identical systems. Cheers. l8er manfred
