systemrescue recently switched from kernel 5.15 to kernel 6.1 and

under gentoo with the same versions for NetworkManager and
linux-firmware than those used in systemrescue (1.42.2 and 20230210).
Under gentoo, the problem appears with kernel 6.1.14 and 6.2.1. I am
able to use NetworkManager and systemrescue without problem on
another computer which has another wifi card.
Does anybody have a solution to this problem ?
François,
Without any log information regarding the specific hang, it will be
difficult to debug this issue.
Have you installed the drivers from the rtw88 repo at GitHub.com? If
so, they may be interfering with the drivers in the kernel. You can
test to see if this is the problem by doing an edit of the command
line while booting. When GRUB is showing the kernel you wish to boot,
press "e". This should bring up a minimal editor. Scroll down until
you find the stanza pertaining to the kernel you are booting. It will
start with "menuentry 'xxxxx'", where the x's are replaced with the
description of the kernel you want.
Once you find that entry, scroll down to the line that starts with
"linuxefi" or "linux", then move to the end of that line, and add
"rd.driver.blacklist=rtw_8723de" to blacklist the driver from GitHub, or
"rd.driver.blacklist=rtw88_8723de" to blacklist the kernel version.
Once you have added the new info, press the F10 key yo continue the boot.
If one of those lets the computer boot, add that driver to a blacklist
file in /usr/lib/modprobe.d/, or wherever your distro keeps the
modprobe.d directory.
If neither work, then report back, and we will try to get a dump of
the logs when the hand happens.

Good evening,
For sure, I am using the kernel driver in gentoo or in systemrescue. Can
you explain how I could obtains the logs when the crash occurs ?
