[bug] Hi, need your help about raid1 causing kernel panic!

[Liam Zeng]

[-- Attachment #1: Type: text/plain, Size: 467 bytes --]

Hope you kindly forgive my troubles. I have worked with a bug for
several days, and I really need your help, even a kind encouragement.

here's some informations
kernel version: 5.10.107
cpu arch: arm64
the system install on /dev/md9, which make up of raid1 of two disks;
the bug: every time I transfer files (50G file, using samba or ftp),
the system will break down.
I have not modified any code of md.

And the attachment is the log.
I would appreciate any reply!

You need to provide more details.  What is your disk setup, what is
your OS base, etc.

Is this is a vendor kernel or your own self-compiled one?  And if so,
can you move to the latest 6.x kernel instead?

More details on this setup.  Type of disks, their connectivity to the
system, etc.

Does it break if you copy the file on the system?  Do you have enough
disk space to copy a 10g file from one directory to another on the
same RAID1 setup?  

Which filesystem are you using?

Good to know.

Sorry, I'm not going to bother decoding it.  Just attach it as plain
text instead please.
