1. Please describe the problem:
I am seeing a large memory spike (19-21gb) when trying to scp a small file 10mb.

2. What is the Version-Release number of the kernel:
6.19.12-300.fc44.x86_64

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :
I have not been able to test since when this problem is present.
I know it's present in the newer linux kernel being used by ubuntu 26.04

4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:
Yes, consistently.
Create a file:
dd if=/dev/urandom of=/tmp/test10m bs=1M count=10
Transfer it:
scp /tmp/test10m any_host:/tmp/test10m

it might take 2-3 transfers for it to trigger.

rsync shows the same behaviour, nc doesn't show it.

5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:
I did not try it.

6. Are you running any modules that not shipped with directly Fedora's kernel?:
No, but I am force probing xe driver instead of i915

7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.
