When I use the SAL layer with Entron cameras with the following parameters:

I see large amounts of text dumped to
sample_kern.log (72.0 KB)

Attached are some sample outputs. The camera still works, but the hard drive eventually runs out of space. I can set up logrotate to mask the issue, but I want to know the root cause of this.

Dear @ylin1,
Could you provide reproducible steps ?


Unfortunately the issue only happens sometimes so I don’t have a way to reproduce the problem reliably. I did attach a sample of what got dumped to kern.log though so if anyone who can parse the log can provide any insight, that would be very helpful.

Hi @ylin1 ,

Please see if Kernel warning "jump label: negative count" helps on the problem. Thanks.

Thanks @VickNV , will follow up after testing it out

I saw your kernel log is from Xavier B.
just curious if this issue is also on Xavier A or camera module other than the Entron one?

Yes, same issue also occurs on xavier a from time to time. we are using Sekonix cameras for xavier a. an example parameter for one of them is
I don’t have a kernel dump handy right now though. I can keep an eye out for when this happens next time on XavierA if you want more data

I asked because the issue had a higher reproducing rate on Xavier B when we looked into it in the other topic.
You can try if the fix helps on your problem here. Thanks.
