It is strange that the bisect is pointing to this commit as reserving a CMA pool and assigning it to a device should be fairly normal usage. Is the issue seen only on OMAP4 Pandaboard and not any of the other OMAP5 uEVM or DRA7xx/AM57xx EVMS? regards Suman > > Thanks, > Guillaume > > On 14/08/2020 15:22, KernelCI bot wrote: >> * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * >> * This automated bisection report was sent to you on the basis * >> * that you may be involved with the breaking commit it has * >> * found.
