[10:28] <xnox> apw, cking - so i upgraded my laptop to a more recent zesty (used to be running 4.8 kernel, and finally got the 4.10 kernel)
[10:28] <xnox> have you been noticing weird stuff going on with nvme drives?
[10:29] <cking> xnox, my NVME drive died a while ago, so I've not seen this
[10:29] <xnox> my controller gives up, and then ext4 goes nuts, fails to write a journal, and then remounts RO and then things fail.
[10:29] <xnox> http://paste.ubuntu.com/24373466/
[10:29] <xnox> well it looks like 4.10 is killing me; or my drive is just dieing.
[10:29] <xnox> but this is like a one year laptop.....
[10:30] <cking> xnox, do you force anything on like PCIe ASPM?
[10:30] <xnox> cking, i'm not sure what you mean.
[10:30] <apw> xnox, well if you are seeing it 'regularly' booting back to a 4.8 kernel would cirtainly tell us if it was 4.10 or not
[10:31] <cking> xnox, if you don't recognise what I'm saying about PCIe ASPM then probably not
[10:31] <xnox> cking, in my bios i can choose driver type for disk drive - e.g. Off, ACHI, Raid (Intel Rapid something bullshit)
[10:31] <xnox> the default for RAID, but linux at the time then did not see any drives
[10:32] <xnox> i am now rebooted into 4.8 and will use 4.8 for now, to see if this is reproducible or not.
[10:32] <cking> xnox, I was wondering if fancy PCIe power saving is making the drive go offline
[10:32]  * xnox ponders if kernel at all is at fault though
[10:32] <xnox> [ 2055.007879] nvme 0000:04:00.0: controller is down; will reset: CSTS=0xffffffff, PCI_STATUS=0xffff
[10:32] <xnox> cannot be kernel initiated can it be? e.g. deciding to power down the drive just for funzies.
[10:32] <xnox> ah that
[10:33] <apw> well it depends what the 'down' in that sentence means
[10:33] <cking> xnox, sometimes the BIOS may hint its fine to do it when in fact it's not
[10:33] <apw> and we might have just started noticing it says we can
[10:34] <xnox> hm
[10:34] <cking> xnox,  "pcie_aspm=off" is the way to force it off just in case
[10:36] <xnox> let me do that in my grub config
[10:42] <xnox> and naturally i have lvm, and full disk encryption
