Public bug reported:
I have rented a dedicated server with fresh installation of Ubuntu
24.04.3 LTS. When I tried to unpack a tar archive, the process hanged up
halfway. I tried to remove the unpacked folder using "rm -rf", but the
command just hanged and did not react to Ctrl+C. I found two kernel
errors in dmesg, first one mentioning "BUG at block/bio.c:1642" with
trace containing functions md_submit_bio and bio_split_to_limits, second
mentioned "kernel/exit.c:821" with trace containing functions
rewind_stack_and_make_dead and make_task_dead. I was not able to
reproduce the error, but a problem that could potentially result in data
loss is extremely concerning. I have checked mdstat (RAID1), it seemed
good with both NVMe disks present, I checked S.M.A.R.T. and ran full
scan on both NVMe, ran memtester and stress-ng, checked ipmitool log and
sensor data, however I was unable to find any hardware issue. If you are
interested in any more details - let me know! For now I assume `ubuntu-
bug linux` has submitted all the info you need. For convenience, here is
the error message I found in dmesg:

kernel BUG at block/bio.c:1642
Status in linux package in Ubuntu:

Bug description:
I have rented a dedicated server with fresh installation of Ubuntu
24.04.3 LTS. When I tried to unpack a tar archive, the process hanged
up halfway. I tried to remove the unpacked folder using "rm -rf", but
the command just hanged and did not react to Ctrl+C. I found two
kernel errors in dmesg, first one mentioning "BUG at block/bio.c:1642"
with trace containing functions md_submit_bio and bio_split_to_limits,
second mentioned "kernel/exit.c:821" with trace containing functions
rewind_stack_and_make_dead and make_task_dead. I was not able to
reproduce the error, but a problem that could potentially result in
data loss is extremely concerning. I have checked mdstat (RAID1), it
seemed good with both NVMe disks present, I checked S.M.A.R.T. and ran
full scan on both NVMe, ran memtester and stress-ng, checked ipmitool
log and sensor data, however I was unable to find any hardware issue.
If you are interested in any more details - let me know! For now I
assume `ubuntu-bug linux` has submitted all the info you need. For
convenience, here is the error message I found in dmesg:
