Problem for testing linux-next
Hi, all. I'm trying to test linux-next. I'm using QEMU for testing. I cloned linux-next repository and checkout to last tag next-20210812. I compiled with simple command below. make menuconfig make & make modules_install & make install and rebooted system. and it failed. It hangs after the message "freeing unused kernel image (init mem) memory" after about 500 seconds, it prints call trace including "x2apic_send_IPI" and it blocked. I want to copy and past it to here. but I don't know how to see the dmesg in last failed session. Is there any wrong configuration for compiling? I would paste it if I could copy the error message. Thanks, Sidong ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

Make sure you have a working configuration based on a released kernel version _first_ (like 5.13), before trying to test linux-next. Once you have that, then take that configuration and use it on the linux-next tree so you know it is not a configuration issue. good luck! greg k-h ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

I reset all the configuration and compiled 5.13 and it works. Also, I compiled with same configuration linux-next and It was OK. Thanks for tip!

kernel / system configuration question regarding "unstable filesystems"
Hello, I'm using a SD card to boot my device. The SD card is connected via a USB-C hub due to the device not having any other connectors. This hub and slot will lose power temporarily if plugging in or unplugging power passthrough to the hub. Then on these events the filesystem becomes unmounted and while my system is still running, it becomes unusable. I get input / output errors for example from the terminal. I think what's going on is some portion of the system is loaded into memory. However many critical parts become unavailable. Then I'm curious what options I have at the kernel or system level to ruggedize this so these events don't destroy the system. Before exposing my own ignorance presenting any ideas with my limited knowledge regarding this topic. Is anyone familiar enough to suggest some design approaches or where I might find the best answer regarding a designed solution? ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
