I have Intel SATA ports configured as AHCI in BIOS with one port designated as hotplug. I use this, connected to an HDD caddy, for hotswap drives as a (non pve storage) backup destination.
Despite some warnings due to incomplete ACPI implementation of this board:
this setup has worked very reliably for a couple of years and through several PVE versions and many kernel upgrades.
However, after upgrading tp pve-kernel-5.13.19-4-pve, I see a kernel OOPS on trying to remove a drive after use.
My procedure has been insert drive, power on caddy, mount partition, run jobs. Then issue this command to park the drive prior to power off:
This generates the exception below. It also occurs if I just power down the drive without first issuing the prior command.
In either case and after the kernel error, the drive remains visible according to
If I boot with pve-kernel-5.13.19-3-pve, no such errors. I'm not sure where's best to report this or if the shortcomings of the old board's BIOS's ACPI have finally caught me out.
