Mark Johnston <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected], | |[email protected] Status|New |Open --- Comment #2 from Mark Johnston <[email protected]> --- I looked at this a bit. For whatever reason, growfs is triggering a DMA transfer of length 512 on a buffer that is not cacheline size-aligned. Because both the beginning and end of the buffer address range are not cacheline size-aligned, the loop in _bus_dmamap_count_pages() concludes that it needs 2 pages in order to bounce the request, but clearly that's not true since the entire request is only 512 bytes. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
