This system have been running following cauldron successfully a half year including kernel 4.8.15-1 but now it fails using kernel 4.9.0-3; in syslog: jan 03 20:16:59 kajsas kernel: BUG: stack guard page was hit at ffffb5b9008f0000 (stack is ffffb5b9008ec000..ffffb5b9008effff) jan 03 20:16:59 kajsas kernel: kernel stack overflow (page fault): 0000 [#1] SMP I tried uninstalling and resinstalling kernel. (it still run OK when booting 4.8.15-1) Other details: Lenovo ThinkPad T60, model 2007FVG; ATI graphics, SSD with LVM but separate /boot.

seem to have been reported upstream at 4.9-rc1 times but no reaction so far.. If you blacklist the modules: tpm_tis tpm_tis_core tpm does it boot up then ?
CC: (none) => tmb
YES :) by adding to kernel boot line manually at grub: modprobe.blacklist=tpm_tis,tpm_tis_core,tpm However now i tried by creating /etc/modprobe.d/blacklist-tpm, containing # mga bug 20071, workaround f kernel 4.9.0-3 @ tmb blacklist tpm blacklist tpm_tis blacklist tpm_tis_core And it do not work, even after reinstalling kernel. What am i doing wrong? Sidenote: on this machine when booting other kernels i have long seen the messages: tpm tpm0: tpm_transmit: tpm_send: error -5 tpm_tis: could not get TPM timeouts and durations
For upstream you mean this report ? : https://lkml.org/lkml/2016/10/24/150 Interesting: That is also a Lenovo Thinkpad T6x... i believe that one have Intel X3100 GPU I have two other thinkpads T61 (type 7665-CTO) and T61p (type 6457-5KG but upgraded with T9500 CPU) that run well with this kernel, some differences against the one in my comment 0 (type 2007FVG) is that they use Nvidia GPU (instead of ATI) and no disk encryption (the one above use ext4 partitions on LVM in one encrypted partition, all set up by diskdrake.) Then there are probably some difference in chips on main board like network, USB, 1394, sound... Oh and all three have a modified (Middleton 2.29) BIOS for faster SATA and some other tweaks; all use SSD.
Another difference is that the laptop where stack overflow happen have a sticker "Duo" while the working laptops stickers say "vPro", which i know implies a more efficient memory buffering etc, so other chipset version.
Still same problem and workaround on 4.9.1-1 ( PS: workaround is to add modprobe.blacklist=tpm_tis,tpm_tis_core,tpm to kernel start parameters using MCC -> start -> configure start system DS ) What are possible implications of blacklisting tpm?
Summary: Kernel 4.9.0-3 kernel stack overflow booting => Kernel 4.9.x kernel stack overflow bootingSource RPM: kernel-4.9.0-3.mga6.src.rpm => kernel-4.9.1-1.mga6.src.rpm
Problem is no more on 4.9.2 :) During booting, at 0:06 i still see the messages - as i have done for long time (when not blacklisting tpm) : tpm tpm0: tpm_transmit: tpm_send: error -5 tpm_tis: could not get TPM timeouts and durations I do not know if that is a sign of some trouble or not. Thomas, tell me if you want me to test something, or you can just close this bug. I will reopen if i see this problem again.
kernel-4.9.3-1 OK too. Closing.
