[Drbd-dev] DRBD broken in kernel 6.5 and 6.5.1

Sat Sep 2 22:31:06 CEST 2023

Hello,

After upgrading the kernel to 6.5 the system can't connect to the peer
(6.4.11) anymore.
I checked 6.5.1 - same issue.
All previous kernels including 6.4.14 are working just fine.
Checking the 6.5 changelog, I found commit
9ae440b8fdd6772b6c007fa3d3766530a09c9045 which mentioned some changes to
DRBD.

On the 6.5.X system I have the following in the kernel log (drbd_send_block()
failed):
