| tomreyn | is this missing / not applied on the 18.04.3 (LTSE/HWE kernel)? https://patchwork.kernel.org/patch/9585671/ | 05:02 |
|---|---|---|
| tomreyn | there's a user reporting running into a "tpm_crb MSFT0101:00 [Firmware Bug]: ACPI region does not cover the entire command/response buffer" message on the 18.04.3 installer running on an 'Alienware R4' gaming laptop. | 05:08 |
| tomreyn | (and how / where would i properly check this myself in the future, not wasting other peoples' time on silly bios bugs) | 05:09 |

| gpiccoli | tomreyn, I've checked Bionic tree and this (kinda old) commit is there, in 4.15, 5.0, 5.3 ... | 11:56 |
| gpiccoli | Is this user reporting the issue running a Canonical bionic kernel? | 11:56 |
| gpiccoli | Also, if you have a Launchpad with this report, let me know the link. If not, you may want to suggest this user to open a LP bug =) | 11:57 |
| tomreyn | gpiccoli: thanks for checking! yes, the user was on a freshly installed ubuntu 18.04.3 with 5.0: https://termbin.com/e3zb | 15:09 |
| tomreyn | i'm not in touch with them anymore, so can't ask for a bug report now, i'm afraid. this dell alienware 17 R4 gaming laptop has a very buggy bios, though. | 15:10 |
| gpiccoli | It seems to hhehe | 15:11 |
| gpiccoli | tomreyn, the fact the message is showing, means the workaround is available, but failed | 15:11 |
| tomreyn | gpiccoli: oh crap, right, the patch actually introduces this message. sorry... | 15:12 |
| gpiccoli | basically, the quirk adds a couple of checks, and if they fail, it prints the message and is conservative about theregion | 15:12 |
| gpiccoli | np tomreyn =) | 15:13 |
| gpiccoli | glad it's figured out | 15:13 |
| * tomreyn blushes | 15:13 | |
| gpiccoli | likely this user has a bugged BIOS as you said | 15:13 |
| tomreyn | yes, and it's the latest they have available for this model | 15:14 |
| tomreyn | we already tried to work around the acpi issues with acpi_osi, but i'm not sure it actually helped | 15:14 |
| gpiccoli | ugh, BIOS issues are always lame to work, vendors are quite difficult to provide data or quickly fix. Dell should be good, perhaps worth to involve them | 15:15 |
| tomreyn | someone poste don their forums about this and other problems in october, no response. | 15:16 |
| tomreyn | https://www.dell.com/community/Alienware/AW17r5-BIOS-Issues/td-p/7391290 | 15:17 |
| gpiccoli | forums are somewhat bad for this, it's my experience also. Perhaps worth to seek vendor official support channels or even a dell kernel devel that works with acpi | 15:17 |
| gpiccoli | git log --oneline --author=\@dell drivers/acpi/ will give you some emails heheh | 15:18 |
| tomreyn | well, i woudn't have such contacts, and the forum would be the standard go-to for customers. either they care or they dont | 15:18 |
| gpiccoli | you can work a goodreport and post to acpi mailing-list, looping the dell developers, likely you'll get some response! | 15:19 |
| tomreyn | i'm not affected by this, so i don't think i'm the right person to do so. also, well, it's a "gaming laptop", those shoould not exist to begin with. | 15:19 |
| tomreyn | thanks for your help, though, i do appreciate it. | 15:20 |
| gpiccoli | haha I agree about "gaming" laptop, I'd not buy such things | 15:22 |
| gpiccoli | you're welcome tomreyn =) | 15:22 |
| gpiccoli | Anytime! | 15:22 |
| tomreyn | :) saying this is dangerous! | 15:22 |
| gpiccoli | hahah | 15:23 |
| * gpiccoli leaving IRC in 3..2.. | 15:23 | |
| gpiccoli | lol | 15:23 |
| tomreyn | :) | 15:23 |
