Bug#910069: linux-image-4.18.0-1-amd64: NVME quirk needed for Intel 760p + Thinkpad T480

2019-02-24 Thread Chris Chiappa 
Doh, I had checked for firmware when I first ran into the problem and
never checked again.  Indeed, having upgraded the firmware, the
command line workaround no longer seems necessary, feel free to close
the bug.  Thanks!

According to the release notes for the Intel SSD Firmware Update Tool

there is a firmware update (version 004C) and the description suggests
it may address this problem.

Please upgrade the firmware (but make sure you have a backup of the
drive) and check whether that fixes the problem.

Ben.

Bug#910069: linux-image-4.18.0-1-amd64: NVME quirk needed for Intel 760p + Thinkpad T480

2018-10-02 Thread Chris Chiappa 
Package: src:linux
Version: 4.18.8-1
Severity: normal

T480 with a SATA SSD works fine out of box.  Replacing the SATA SSD
with an Intel 760p, the latest Buster installer gets the system
installed fine, but it is extremely unstable after rebooting into the
new installation.  There's a "dmesg" output I was able to get from one
such hang.  When the drive hangs, on reboot the BIOS is not even able
to see it.

Googling turns up nothing about this particular combination, but there
are other (presumably more popular) NVME SSDs that exhibit similar
problems:

https://askubuntu.com/questions/905710/ext4-fs-error-after-ubuntu-17-04-upgrade/906105#906105
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184
https://lkml.org/lkml/2017/5/24/941

I've confirmed that with the kernel flag
nvme_core.default_ps_max_latency_us=5500 the machine is stable.

It seems like there are some SSDs that always need
NVME_QUIRK_NO_DEEPEST_PS and there are some for which it's only a
specific combination of SSD and machine.  I don't have any other NVME
capable machines here so don't know if I can determine that.  Happy to
do more debugging if there's anything I can provide.  As far as I can
tell, there is no firmware update for this drive available.
