--- Comment #12 from LTC BugProxy
Just let me confirm again: since transparent_hugepage=never is active, no oops has happend. Looks like there is some issue there.
If you have some more ideas how to debug that further, please tell me. BTW: I am not that much into other architectures. But from what I saw so far, those issues did not happen on other architectures (all of which seem to be little endian tough).
Thanks, that narrows it down. Could you please attach the exact kernel config that was used, or can it be found somewhere (I only know how to find it for SLES)? Also, any information could be useful which would narrow down the affected kernel version. Unfortunately, it seems that we cannot reproduce this easily to verify if it is also an issue in upstream kernel and do a bisect. So far, we know from the backtrace that it happened on a 5.5.2-1 kernel, and you also wrote "Since php7:test is quite late in the build tree, I guess that this problem was introduced with Kernel 5.5.1". Did it ever work with a 5.5.x kernel, if not, which was the last working version? Last but not least, a dump could still be useful, but I also need the corresponding vmlinux files with and without debuginfo for analysis. -- You are receiving this mail because: You are on the CC list for the bug.
