The assertions in storvsc_xferbuf_prepa= re() are disabled on arm64 in commits 6f7b1310b6fe3 and 0af5a0cd2788e with no re= al explanation given, so I somewhat suspect that the crash is unrelated. (Actually I am not sure how busdma can be forced to make each segment a multiple of the page size, but this certainly appears to be a requirement of the driver, since the callback does not store the segment length anywhere..= .) --=20 You are receiving this mail because: You are the assignee for the bug.=
