[06:15] <PaulePanter> Hi. What is the official Canonical/Ubuntu Linux kernel git archive/repository?
[06:16] <PaulePanter> https://kernel.ubuntu.com/git/?s=idle
[06:21] <juergh> PaulePanter: See the messages right before yours.
[06:22] <PaulePanter> juergh: I just joined.
[06:22] <PaulePanter> … the channel.
[06:24] <juergh> https://irclogs.ubuntu.com/
[06:24] <juergh> specifically https://irclogs.ubuntu.com/2023/02/27/%23ubuntu-kernel.html
[06:27] <PaulePanter> juergh: Thank you.
[06:31] <PaulePanter> Alright, it looks like Ubuntu/Canonical does not extend the accelerotmeter address list for Dell laptops.

[06:33] <PaulePanter> The Dell Precision 3540 is certified with Ubuntu: https://ubuntu.com/certified/201902-26859
[06:33] <PaulePanter> but Linux logs the warning
[06:33] <PaulePanter> Accelerometer lis3lv02d is present on SMBus but its address is unknown, skipping registration

[06:33] <PaulePanter> Does Canonical/Ubuntu have access to the schematics/documentation to find out the I2C address?
[06:34] <juergh> you could probe the bus
[06:35] <juergh> i2cdetect
[06:35] <PaulePanter> juergh: Yes, Wolfram responded the same.
[06:35] <juergh> and?
[06:36] <juergh> did you try that?
[06:36] <PaulePanter> juergh: But why should I, if I pay money for the device shipped with Ubuntu, and Dell has that information.
[06:36] <PaulePanter> juergh: No, the device is at work, and actually in production use by a user.
[06:37]  * PaulePanter still hasn’t figured out, how the cooperation between Canonical and Dell works. Dell at least makes some kind of money selling devices advertised with GNU/Linux (Ubuntu) support.
[06:38] <PaulePanter> But they don’t seem to even run `dmesg --level=alert,crit,err,warn` to check the support.
[06:51] <juergh> Your best bet is to open an LP bug.
[11:10] <alkisg> [ 6878.377221] sr 1:0:0:0: [sr0] tag#19 unaligned transfer, [ 6878.377223] blk_update_request: I/O error, dev sr0, sector 6 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 0, [ 6878.377227] Buffer I/O error on dev sr0, logical block 6, async page read
[11:10] <alkisg> ==> Hi, after this or the previous kernel updates, I see these errors in many different PCs with Ubuntu 22.04, and on both the 5.19.0-32 and then 5.15.0-60 kernel. There is NO cdrom inserted when these messages appear. The result is that the PC is veeeery slow, similar to having 100% disk usage
[11:10] <alkisg> Is it a known issue, any LP bugs about it that I could monitor?
[11:14] <PaulePanter> juergh: With Wolfram’s help, 0x29 is the right address: https://lore.kernel.org/all/97708c11-ac85-fb62-2c8e-d37739ca826f@molgen.mpg.de/
[11:15] <PaulePanter> juergh: I am going to create a Launchpad ticket nevertheless, asking to check such things in the future, that means, making it part of the certification process.
[11:21] <juergh> alkisg: Was this introduced in 5.15.0-60?
[11:22] <alkisg> juergh: either in 5.19.0-32 and 5.15.0-60, or the ones right before them
