In case anyone finds this bug report when googling for this error: the problem is that the hpsa driver (which drives many HP RAID controllers) just doesn't support suspend.
The code (even in Linux 5.0.13) reads: ``` static int hpsa_suspend(__attribute__((unused)) struct pci_dev *pdev, __attribute__((unused)) pm_message_t state) { return -ENOSYS; } static int hpsa_resume(__attribute__((unused)) struct pci_dev *pdev) { return -ENOSYS; } static struct pci_driver hpsa_pci_driver = { .name = HPSA, .probe = hpsa_init_one, .remove = hpsa_remove_one, .id_table = hpsa_pci_device_id, /* id_table */ .shutdown = hpsa_shutdown, .suspend = hpsa_suspend, .resume = hpsa_resume, }; ``` -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1579410 Title: Cannot suspend HP ProLiant SE316M1R2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1579410/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
