Test Fix
The patch I just attached about this may fix your issue. Seems to work now thank you very much. do you think your patch will be included on 4.x kernels? Created attachment 209781 [details]
Test Patch
If you are willing to test the patch against main line kernel just o make sure it's just fine. I also rewrote the patch with a commit log now just add your tested by below it. sorry I can't have access to the log anymore... The kernel log or the bug log. Sorry do you mean the bug log or the kernel bugzilla log? just today my data center blocked my server where the card is because of invoice contentious... a kind of conspiracy against my project.... That's OK :). If you can however add tested by on my patch I would really appreciate it. I just had time yesterday to check the log and see that the errors disappear. today no ssh access at all. anyhow it's months now they are creating troubles against me so I just give up and ask my money back next week. cheers how can I mark tested on your patch? Just type the line: Tested-by: Your Full Name email address Tested-by: Orion admin@e-blokos.com And if you do get around to it try testing on mainline. Personally I wrote the patch on mail line so if it applies clearly to your kernel it possibly works fine on main line but just doubt check if you can. ok thanks. the best would be to check if another guys can test it also I think Christoph Hellwig already fixed this issue in the upstream kernel, with these 2 upstream patches: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=118c855b5623f3e2e6204f02623d88c09e0c34de https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=15e3d5a285ab9283136dba34bbf72886d9146706 I would apply the above 2 patches to your kernel and try to reproduce. Those patches may fix it but I am pretty sure those patches are in the 3.18.3 kernel release back port. Maybe I am work but let Orion test those patches too to see if those should be back ported or are already there. Unfortunately for now my DC blocked all ssh access and I'm afraid it's for a long time... |
