[06:15] Hi. What is the official Canonical/Ubuntu Linux kernel git archive/repository? [06:16] https://kernel.ubuntu.com/git/?s=idle [06:21] PaulePanter: See the messages right before yours. [06:22] juergh: I just joined. [06:22] … the channel. [06:24] https://irclogs.ubuntu.com/ [06:24] specifically https://irclogs.ubuntu.com/2023/02/27/%23ubuntu-kernel.html [06:27] juergh: Thank you. [06:31] Alright, it looks like Ubuntu/Canonical does not extend the accelerotmeter address list for Dell laptops. [06:31] https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/lunar/tree/drivers/i2c/busses/i2c-i801.c?id=ab2e786e8b1e6690c98424277abe512970850bd6 [06:33] The Dell Precision 3540 is certified with Ubuntu: https://ubuntu.com/certified/201902-26859 [06:33] but Linux logs the warning [06:33] Accelerometer lis3lv02d is present on SMBus but its address is unknown, skipping registration [06:33] https://lore.kernel.org/all/97708c11-ac85-fb62-2c8e-d37739ca826f@molgen.mpg.de/ [06:33] Does Canonical/Ubuntu have access to the schematics/documentation to find out the I2C address? [06:34] you could probe the bus [06:35] i2cdetect [06:35] juergh: Yes, Wolfram responded the same. [06:35] and? [06:36] did you try that? [06:36] juergh: But why should I, if I pay money for the device shipped with Ubuntu, and Dell has that information. [06:36] 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] But they don’t seem to even run `dmesg --level=alert,crit,err,warn` to check the support. [06:51] Your best bet is to open an LP bug. [11:10] [ 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] ==> 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] Is it a known issue, any LP bugs about it that I could monitor? [11:14] 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] 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] alkisg: Was this introduced in 5.15.0-60? [11:22] juergh: either in 5.19.0-32 and 5.15.0-60, or the ones right before them === magali is now known as mlemes [12:29] juergh: https://answers.launchpad.net/ubuntu-certification/+question/705643 === alkisg1 is now known as alkisg
