https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219857 --- Comment #10 from Kenneth D. Merry <ken@FreeBSD.org> --- Created attachment 195055 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D195055&action= =3Dedit Proposed patch to make the media check async Here is a proposed patch against FreeBSD/head as of revision 335477 on June 21st, 2018. This makes the media check process asynchronous, so we no longer block in cdstrategy() to check for media. This still needs some additional testing in various situations. I think th= ere may still be one panic (GEOM assertion I believe) I saw with an audio CD in= a drive, and I have not tested this with a SCSI CD/DVD drive. I have only tested so far with a SATA drive running ATAPI. In any case, give this a try and let me know if it improves things for you. --=20 You are receiving this mail because: You are on the CC list for the bug.=
