Bug#949020: linux-image-5.6.0-2-amd64: Lenovo poweroff/suspend failure
Hi! I have the exact same problem on a fresh Debian 11 installation and a T460s laptop. Changing TPM from 2.0 to 1.2 in the BIOS resolves the poweroff and the suspend issue. Also FYI (not sure if that helps), as I did not found 949020 earlier, I have used the following workaround on Buster + 5.10 bpo kernel (hibernating just after booting to then be able to suspend until next reboot): | echo reboot >/sys/power/disk | echo disk >/sys/power/state As far as I can remember, I did not had the poweroff problem on Buster, just suspend. -- Faustin signature.asc Description: PGP signature
Bug#990868: lenovo T460 Shutdown Problem
Hi Bjørn! Bjørn Mork , 25/08/2021 – 20:12:09 (+0200): > This sounds like https://bugs.debian.org/949020 Yes, exactly! I remember searching a lot when it happened to me last year, but not sufficiently apparently... > Short version: Disable TPM 2.0 (select 1.2) i BIOS, or disable IOMMU by > booting with intel_iommu=off on the command line. Switching to TPM 1.2 works perfectly, I did not tried the intel_iommu=off workaround so far... Thanks again! -- Faustin signature.asc Description: PGP signature
Bug#990868: lenovo T460 Shutdown Problem
Hi! I seem to have the same problem on my T460s and it is impossible to suspend the laptop (lid close or systemctl suspend). As far as I can remember, the problem appeared with kernel 5 branch (bpo on buster). At that time I did not wanted to open a bug report because I was not sure of my installation (dist-upgrade from buster, plus lots of bpo kernel installation and test) and I had found a workaround for the suspend problem, using those commands after reboot: | echo reboot >/sys/power/disk | echo disk >/sys/power/state Now I have a clean Debian 11 installation and both suspend and poweroff does not work anymore. I am happy to help to debug this if needed. Cheers! Faustin signature.asc Description: PGP signature
Bug#696059: linux: PATCH required for server interrupt load balancing/irqbalance (tested)
Dear maintainer, I must agree with Sebastian Kutsch. irqbalance may not be the better way to treat interruption problem but it is doing is job quite good on a (squeeze - 3.2.0-0.bpo.4-amd64). Regards, Faustin LAMMLER http://www.falared.net
