https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D265786 Bug ID: 265786 Summary: broadcom storage controller: bus_dmamap_load_ccb() is failing with EINPROGRESS for 1MB IOs Product: Base System Version: 13.1-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: chandrakanth.patil@broadcom.com We are seeing the issue in bus_dmamap_load_ccb() function in the case of 1MB IOs.=20 It seems, that IO mapping to DMA mem is taking more time so bus_dmamap_load= _ccb is returning EINPROGRESS (error no: 36) more frequently. the DMA attributes passed are below while creating the tag: 1. maxsize: 1MB 2. nsegments: 256 3. maxsegsz: 1MB I have seen in some of the FreeBSD BZ that warner losh has suggested the workaround for this by increasing the hw.maxphys in /boot/loader.conf. I ha= ve tried the same and it will fix our issue. but the issue was reported on 13.0 and the fix was supposed to be part of 13.1 but I am still seeing it. --=20 You are receiving this mail because: You are the assignee for the bug.=
