I don't have official recommendations, nor HW to test at the moment, but for the record, Peach Pi should have Marvell SD 8797. You can see what firmware Chrome OS used to ship for those devices here: https://chromium.googlesource.com/chromiumos/third_party/marvell/+/HEAD/sd8797_uapsta.bin https://chromium.googlesource.com/chromiumos/third_party/marvell/+log/HEAD/sd8797_uapsta.bin Notably, the versioning there (e.g., W14-66-27-p18) suggests it's a different branch (?) than what's currently provided in the main linux-firmware (W14.68.29.p59). So you might give a try at replacing the file in /lib/firmware/mrvl/. No guarantees though. > kernel is mainline 5.14.4 without patches, but I recall that I noticed > this crashes on older ones but can't remember exact version. Did it ever work well? I'm curious if this was a kernel regression, or perhaps just a long-standing firmware issue. Brian
