Package: src:linux
Version: 6.7.9-2
Severity: important
X-Debbugs-Cc: fores...@sonic.net
Dear Maintainer,
The current debian unstable kernel causes a variety of failures that are not
present in the bookworm kernel, on the RockPro64 single board computer. (This
is an arm64 machine built upon the Rockchip rk3399 SoC.)
The system is sometimes able to reach a state where sshd login works, allowing
me to run reportbug, but not always. Regardless of whether it gets that far,
dmesg often contains one or more stack traces, along with messages like these:
kernel BUG at mm/slub.c:448!
Internal error: Oops - BUG: f2000800 [#1] SMP
WARNING: CPU: 2 PID: 0 at kernel/context_tracking.c:128
ct_kernel_exit.isra.0+0xa0/0xa8
Unable to handle kernel paging request at virtual address 4daee1bbcd3980fb
I have noticed es8316 driver error messages preceding some of these stack
traces, though I'm not sure if that is always the case.
Sometimes the stack traces appear only once, during boot, and the system
appears to run normally after that. Other times, they appear every few minutes,
and various things like network services and the ability to cleanly shut down,
or even log in at the serial console, fail. In one case, I noticed a message
mentioning a kernel panic in the serial console output when I was trying to
shut down.
Since the worst examples of failure prevent me from logging in, I am unable to
run reportbug to capture information about those cases.
Reverting to linux-image-6.1.0-20-arm64 solves the problem.
