[opensuse-kernel] Failed to start Load Kernel Modules

I have many openSUSE installations. I routinely see $SUBJECT on various hosts. What is the pciehp module for? Is this a bug that needs a report? B.O.O. search Summary: pciehp Classification: openSUSE Changed: (is greater than or equal to) 5m produces Zarro Boogs found. Below is from kernel 4.12.14...12.19 in 15.0.

[opensuse-kernel] netconsole problems
by don fisher 13 Oct '18

13 Oct '18

I am looking for assistance in running netconsole. I am trying to run the statically linked version since I am trying to record the screen dump that occurs with crashes during boot. In summary, my netconsole appears to work fine, but it hangs before the output matches that presented by dmesg. If I run the module version, it behaves as expected printing messages from "modprobe floppy" and others suggested on the net. The static version is silent, until I issue a command to generate a panic, "echo c > /proc/sysrq-trigger". I have looked at the code and get lost trying to determine what is not happening. This is too early in the boot process and there are too many spinlocks. I assume that this is interrupt driven, but cannot isolate the logic. I am currently running opensuse 42.3 with a 4.18.7 kernel. This situation is repeatable. The command on the linux boot line includes: netconsole=64001@192.168.7.60/eth0,64001@192.168.7.55/34:e6:d7:01:2a:dd The command at my receiver is: sudo nc -v -u -l 64001 | tee netconsole.log AS indicated before, all the above appears to work until the hang, so I think my setup is correct. Is there anybody that would venture to experiment and see if this also happens to somebody else? I have tried asking on kernelnewbies and even sent an email to the maintainer, but have received no adequate response. Any suggestion would be appreciated. I will offer any other info I may have omitted. Don -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] kmalloc-2048 memleak in 4.19rc kernels
by Stefan Seyfried 10 Oct '18

10 Oct '18

Hi, I think I'm seeing a continuously rising usage of kmalloc-2048 slabs in /proc/slabinfo and slabtop. Before I rebooted from 4.19rc3 to 4.19rc5, I had about 4.5GB of kmalloc-2048 after about 13d8h uptime. Now, after almost 10 minutes uptime, it has already grown to 4MB: 2166 2166 100% 2.00K 1083 2 4332K kmalloc-2048 How can I debug this? The usage started to increase immediately after boot into an idle XFCE desktop, running a small X11 application (gkrellm system monitor) via SSH on a remote machine After disabling networking in NetworkManager, kmalloc-2048 usage went down (from about ~2500 objects to 2388 active objects right now), now on a stable, lightly fluctuating level. This is a Lenovo Thinkpad T420, Core i5-2520M CPU, 8GB RAM, Intel Centrino Advanced-N 6205 [Taylor Peak] WIFI module, Ethernet unused. Once I know how to find out more details, I'm ready to report this upstream ;-) Thanks, Stefan -- Stefan Seyfried "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." -- Richard Feynman -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] Removal of f2fs
by Nikolay Borisov 01 Oct '18

01 Oct '18

Hello everyone, I'm writing this to announce that I intend on removing f2fs being built as part of opensuse-leap and opensuse-tumbleweed kernels. The reasoning behind this can be found at https://bugzilla.opensuse.org/show_bug.cgi?id=1109665. Additionally I'd like to use this email as an opportunity for everyone who might be negatively impacted by this change to voice their concern. If I hear nothing in 2-3 days I shall proceed forward and apply the necessary changes to the kernel config.
