Package: linux-image-amd64 Version: 4.9+80+deb9u1 Severity: normal Hi, I find that the tpm_tis.ko module is missing in all kernel packages since 4.9.0-3 (which is the version in Debian 9 installers and the security archive). This includes all more recent kernels that I've tried from unstable. It was present in 4.9.0-2 which makes me wonder if it was removed due to some last minute security problem before the release of Debian 9. However this is a severe problem for users of the 2013 Chromebook Pixel as there was a firmware bug that means suspend/resume doesn't work unless the tpm chip has been initialized by the module. In other words suspend/resume is broken on the 2013 Pixel ever since 4.9.0-3 but worked fine previously. I can't find an existing bug about tpm_tis or any mention of it on the list. Perhaps this was done unintentionally? -- System Information: Debian Release: 9.1 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8), LANGUAGE=en_CA.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages linux-image-amd64 depends on: ii linux-image-4.9.0-3-amd64 4.9.30-2+deb9u3 linux-image-amd64 recommends no packages. linux-image-amd64 suggests no packages. -- no debconf information

I don't believe such a failure would be related to the tpm_tis driver, since as I said it is still included. > I can't find an existing bug about tpm_tis or any mention of it on the > list. Perhaps this was done unintentionally? We didn't deliberately change it to built-in, but this is a result of enabling IMA. Ben. -- Ben Hutchings Make three consecutive correct guesses and you will be considered an expert.
