Created attachment 764447 [details] .config Kernel hangs on boot. Previous gentoo-sources-5.15.16 works just fine. Config for gentoo-sources-5.15.19 (attached) was made using `make oldconfig` from 5.15.16's config. Config files are the same (excluding kernel version in top comment). I'll attach photos of hang kernel output.

Just tried sys-kernel/gentoo-sources-5.15.21 with same .config - it hangs in same way as sys-kernel/gentoo-sources-5.15.19. :(
sys-kernel/vanilla-sources-5.15.21 hangs in same way. May be related: https://www.reddit.com/r/Fedora/comments/shhj6e/kernels_above_51516_are_crashing/ https://issues.guix.gnu.org/53712

Vanilla kernel 5.15.16 works, 5.15.17 hangs.
if you're feeling particularly ambitious, you could try a bisect between 5.15.16 and 5.15.7 ... perhaps something like https://wiki.gentoo.org/wiki/Kernel_git-bisect or http://www.reactivated.net/weblog/archives/2006/01/using-git-bisect-to-find-buggy-kernel-patches/ with the actual commit that introduces the failure, it will be a lot easier for upstream (or us) to help. it looks like maybe 842 commits, which seems like a lot, but a bisect should be able to cover it in 10 steps.
(In reply to Greg Kubaryk from comment #9) > if you're feeling particularly ambitious, you could try a bisect between > 5.15.16 and 5.15.7 ... perhaps something like Just finished bisecting. First commit which result in hang is: e23f075d7798 - iwlwifi: fix leaks/bad data after failed firmware load
Reverting that commit on sys-kernel/gentoo-sources-5.15.19 fixes the hang.
Here is minimal patch which fixes the hang: --- a/drivers/net/wireless/intel/iwlwifi/iwl-drv.c 2022-02-06 13:34:45.707957370 +0200 +++ b/drivers/net/wireless/intel/iwlwifi/iwl-drv.c 2022-02-06 13:57:23.840000583 +0200 @@ -1616,7 +1616,7 @@ device_release_driver(drv->trans->dev); free: if (failure) - iwl_dealloc_ucode(drv); + iwl_drv_stop(drv); if (pieces) { for (i = 0; i < ARRAY_SIZE(pieces->img); i++) WARNING: I'm not a kernel developer (or even C developer), this change was just a random guess, I do not really know what I'm doing here. :)
(In reply to Alex Efros from comment #12) > Here is minimal patch which fixes the hang: Oops, it wasn't that easy. While it actually fixes the hang on boot, my fix result in hang on shutdown/reboot (probably because iwl_drv_stop() is called again on shutdown).
Created attachment 764472 [details, diff] /etc/portage/patches/sys-kernel/gentoo-sources-5.15.19/fix-iwlwifi-hang.patch Revert (most of) kernel commit e23f075d7798 to fix hang on boot.

So this happened to me and I did the same bisect you did. I ended up taking CONFIG_IWLWIFI out of my .config (since the system in question did not have WiFi anyways). Do you need IWLWIFI support?
(In reply to Mike Pagano from comment #15) > I ended up taking CONFIG_IWLWIFI out of my .config (since the system in > question did not have WiFi anyways). > > Do you need IWLWIFI support? I'm not sure about my system - accordingly to `lspci -k` my motherboard has: 04:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a) which currently doesn't use any kernel driver and thus probably doesn't work. Related kernel setup is: <*> Intel Wireless WiFi Next Gen AGN - Wireless-N/Advanced-N/Ultimate-N < > Intel Wireless WiFi DVM Firmware support <*> Intel Wireless WiFi MVM Firmware support But I'm supporting Gentoo on several other servers and workstations which might use it, so it's better to have this issue patched than hope on disabled kernel options in config.

Test it anyways.
Yes, but ultimately, Gentoo isn't going to be the one to patch the issue for real, so we need to collect data to have a good bug report for upstream. That's why mpagano is telling you to test it anyway, it's not about a lame workaround..

Yes, disabling this kernel option also fixes this issue and result in normal boot (kernel without the patch). Here is .config diff (only one option was switched off manually): --- .config 2022-02-07 16:11:37.397018032 +0200 +++ .config 2022-02-07 16:03:15.354296783 +0200 @@ -1608,9 +1608,7 @@ # CONFIG_FW_LOADER_COMPRESS is not set # end of Firmware loader -CONFIG_WANT_DEV_COREDUMP=y CONFIG_ALLOW_DEV_COREDUMP=y -CONFIG_DEV_COREDUMP=y # CONFIG_DEBUG_DRIVER is not set # CONFIG_DEBUG_DEVRES is not set # CONFIG_DEBUG_TEST_DRIVER_REMOVE is not set @@ -2382,18 +2380,7 @@ # CONFIG_IPW2200 is not set # CONFIG_IWL4965 is not set # CONFIG_IWL3945 is not set -CONFIG_IWLWIFI=y -CONFIG_IWLWIFI_LEDS=y -# CONFIG_IWLDVM is not set -CONFIG_IWLMVM=y -# CONFIG_IWLWIFI_BCAST_FILTERING is not set - -# -# Debugging Options -# -# CONFIG_IWLWIFI_DEBUG is not set -# end of Debugging Options - +# CONFIG_IWLWIFI is not set CONFIG_WLAN_VENDOR_INTERSIL=y # CONFIG_HOSTAP is not set # CONFIG_HERMES is not set

Created attachment 764620 [details, diff] iwlwifi: fix use-after-free This applies and fixes the issue for me with 5.16.7. I did not yet boot test this with 5.15.21, but it does apply and compile

This will be in gentoo-sources-5.16.8 and 5.15.22
