Hi, I notice a bug report on Bugzilla [1]. Quoting from it: > Hello guys, > > marvell sas driver fails to resume from suspend/hibernate properly and the disks disappear. The issue most likely affects all the chips supported by this driver. > > For the first test, I booted the system with 2 ATA disks attached to the onboard SAS controller and did a suspend/resume cycle followed by a get health info cmd. > For the second test, I booted the system with a SAS disk attached to the onboard SAS controller and did a hibernate/resume cycle followed by a gnome disks read cmd. > The boot drive is not attached to the marvell sas controller. > > When I try to access the disks after resuming from suspend/hibernate the system becomes dead slow and the disks show no sign of life. > The system cannot power off by itself at this stage, it needs a hard reset or a power off by the psu switch. > > The most important parts of the kernel log can be found below. > I have provided mainly the mvsas messages and those that have to do with the suspend/resume. > > Suspend/resume with ata disks and then trying to get health info: > > [ 0.000000] Linux version 6.1.57-vanilla (turbo@dbn-003) (gcc (Debian 12.2.0-14) 12.2.0, GNU ld (GNU Binutils for Debian) 2.40) #14 SMP PREEMPT_DYNAMIC Sat Oct 14 11:48:05 EEST 2023 > [ 0.000000] Command line: BOOT_IMAGE=/vmlinuz-6.1.57-vanilla root=/dev/mapper/test-root ro quiet > > [ 0.345919] pci 0000:06:00.0: [11ab:6440] type 00 class 0x010400 > [ 0.345956] pci 0000:06:00.0: reg 0x18: [io 0xbc00-0xbc7f] > [ 0.345980] pci 0000:06:00.0: reg 0x20: [mem 0xfbaff000-0xfbafffff 64bit] > [ 0.345991] pci 0000:06:00.0: reg 0x30: [mem 0xfba80000-0xfbabffff pref] > [ 0.346048] pci 0000:06:00.0: supports D1 > [ 0.346049] pci 0000:06:00.0: PME# supported from D0 D1 D3hot > [ 0.346078] pci 0000:06:00.0: 2.000 Gb/s available PCIe bandwidth, limited by 2.5 GT/s PCIe x1 link at 0000:00:1c.4 (capable of 8.000 Gb/s with 2.5 GT/s PCIe x4 link) > [ 0.346130] pci 0000:06:00.0: disabling ASPM on pre-1.1 PCIe device.
