--- Comment #11 from Erhard F. (erhar...@mailbox.org) --- (In reply to Christophe Leroy from comment #10) > I'm wondering whether you could be running out of vmalloc space. I initially > thought you were using KASAN, but it seems not according to your .config. Correct, I was not using KASAN. I use it only for testing -rc kernels or when I am particularly wary. This memory corruption I noticed during regular usage. Seems running the kernel with slub_debug=FZP page_poison=1 is a good thing. ;) > Could you try reducing CONFIG_LOWMEM_SIZE to 0x28000000 for instance and see > if the memory corruption still happens ? Thanks, that did the trick! With CONFIG_LOWMEM_SIZE=0x28000000 the memory corruption is gone on VMAP_STACK enabled kernels. Tested it additionally on current 5.16.4 where this works too. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
