Hi
    We're upgrading our systems from using a 5.1.7 based kernel to a 
6.3.1 based kernel.
I'm experiencing some warnings popping out occasionally from the f2fs driver

This is after performing a format on the device in system to make sure 
the filesystem was up to the same kernel revision.
How concerned should we be?

Note prior to the format we were getting a LOT or errors, some like 
above and others with a different signature:

****************************************************************************************

__insert_extent_tree+0x15c/0x174
****************************************************************************************

That one resulted in the entire system coming to a a halt..

Cheers

Hi,

Could you please consider v6.3.3 which has some fixes?

Thanks,

Hi Kim
      Sorry about the slow reply. Had to get a UART issue out of the way before I could test this at 6.3.3
Indeed things seem to be ok again.
So can close this issue.

Cheers
