[Bug 1891773] Re: kcompactd0 and btrfs-transaction keep deadlocking with each other

2020-09-14 Thread Miroslav Goldgamer

For some time now I thought the issue is related to the storage for few months 
now.
I currently have a system with -113 kernel and btrfs running for over 30 days 
but other systems with this kernel had issues. In other hand - previous kernels 
had issues (since 106 or so)

[Bug 1756315] Re: fstrim and discard operations take too long to complete - Ubuntu 16.04

2020-09-14 Thread Matthew Ruffell

Hello Alexandre,

I tried to reproduce this bug, and I believe it has been fixed.

I started a i3.4xlarge instance on AWS, with Xenial as the distro:

$ uname -rv
4.4.0-1112-aws #124-Ubuntu SMP Fri Jul 24 11:10:25 UTC 2020

>From there, I checked the NVMe disks:

$ lsblk
NAMEMAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
xvda202:008G  0 disk 
`-xvda1 202:108G  0 part /
nvme0n1 259:00  1.7T  0 disk 
nvme1n1 259:10  1.7T  0 disk

Made a Raid 0 array:

$ sudo mdadm --create --verbose --level=0 /dev/md0 --raid-devices=2 
/dev/nvme0n1 /dev/nvme1n1
mdadm: chunk size defaults to 512K
mdadm: Defaulting to version 1.2 metadata
mdadm: array /dev/md0 started

And formatted it:

$ time sudo mkfs.xfs /dev/md0
meta-data=/dev/md0   isize=512agcount=32, agsize=28989568 blks
 =   sectsz=512   attr=2, projid32bit=1
 =   crc=1finobt=1, sparse=0
data =   bsize=4096   blocks=927666176, imaxpct=5
 =   sunit=128swidth=256 blks
naming   =version 2  bsize=4096   ascii-ci=0 ftype=1
log  =internal log   bsize=4096   blocks=452968, version=2
 =   sectsz=512   sunit=8 blks, lazy-count=1
realtime =none   extsz=4096   blocks=0, rtextents=0

real0m24.414s
user0m0.000s
sys 0m7.664s

I also tried to fstrim:

$ sudo mkdir /mnt/disk
$ sudo mount /dev/md0 /mnt/disk
$ sudo fstrim /mnt/disk
$ time sudo fstrim /mnt/disk

real0m22.083s
user0m0.000s
sys 0m7.560s

Things seem okay, I think this has been fixed somewhere between 4.4.0-1052-aws
and 4.4.0-1112-aws. 

I'm going to mark this bug as fixed released, but let me know if you still have
problems.

[Bug 1895612] Re: Dynamically set AD5593R channel modes

2020-09-14 Thread AceLan Kao

** Description changed:

  [Impact]
  On Advantech UNO-420 development platform, we need a generic way to set the 
pin mode.
+ Upstream would like us to leverage ACPI override method to change the modes, 
but in Ubuntu core, we can't generate a new initramfs and boot up with the 
generated initramfs.
  
  [Fix]
  Add a module parameter to assign pin modes while loading ad5593r driver.
  
  [Test]
  Verified on Advantech UNO-420 platform.
  
  [Regression Potential]
- Low,
+ Low, it checks the length of the passed parameter, and checks every bytes in 
it to make sure it's a valid argument.

[Bug 1861610] Re: 'Elan touchpad' not detected on 'Lenovo ThinkBook 15 IIL'

2020-09-14 Thread Irwan Oyong

Hi! Thank you guys for the thread and hardwork.

I am using Ubuntu 20.04 on Lenovo Yoga Slim 7 (14IIL05). The touchpad
was not detected initially, so I installed Kai's kernel
https://people.canonical.com/~khfeng/lp1853277-final/ and now it worked,
but the downside is, my NVIDIA graphic card is not working. The driver
is still detected, but
