It was working in 2.6.32 but has been broken from kernel 3 onwa= rds. 2.6.32 was released in 2009, and 3.0 was released in 2011. Can you please try a more modern kernel like 5.15, or ask for support from the vendor that is forcing you to use older kernels? Or, can you use 'git bisect' between the working and failing kernel versions to track down the offending commit? thanks, greg k-h --=20 You may reply to this email to add a comment.
