>Number: 184530 >Category: kern >Synopsis: Booting FreeBSD 10.0-BETA4 / 11-CURRENT fails under Parallels on OSX with empty virtual DVDROM >Confidential: no >Severity: non-critical >Priority: low >Responsible: freebsd-bugs >State: open >Quarter: >Keywords: >Date-Required: >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Fri Dec 06 06:00:00 UTC 2013 >Closed-Date: >Last-Modified: >Originator: Karl Pielorz >Release: 11-CURRENT >Organization: >Environment: FreeBSD 11.0-CURRENT FreeBSD 11.0-CURRENT #2 r259015: Fri Dec 6 05:01:36 UTC 2013 root@:/usr/obj/usr/src/sys/GENERIC adm64 >Description: Both FreeBSD 10.0-BETA4 and 11-CURRENT both fail at boot time if you have an empty virtual DVDROM attached to the system (this doesn't even have to be marked as 'Connected' in Parallels - just present in the virtual machine hardware list). The DVDROM probes as: cd0 at ahcich1 bus 0 scbus3 target 0 lun 0 cd0: < Virtual DVD-ROM R103 > Removable CD-ROM SCSI-0 device cd0: Serial Number - xxxxxxx cd0: 150.000MB/s transfers (SATA 1.x, UDMA1, ATAPI 12bytes, PIO 8192bytes) cd0: cd present [1 x 0 byte records] random: unblocking device. Netvsc initializing... SMP: AP CPU #1 Launched! SMP: AP CPU #2 Launched! SMP: AP CPU #3 Launched! WARNING: WITNESS option enabled, expect reduced performance. With no 'media' in the virtual drive - that's as far as you'll get booting - after a long time out you'll then get the following logged: ahcich1: Timeout on slot 0 port 0 ahcich1: is 00000000 cs 00000000 ss 00000000 rs 00000003 tfd 2051 serr 00000000 cmd 1000c013 That just repeats. If you *have* virtual media in the DVDROM drive the system sometimes throws one of the timeouts similar to the above - but will boot. With media in the drive - the kernel output at boot shows: cd0: cd present [1306092 x 2048 byte records] Without media that bit shows as: cd0: cd present [1 x 0 byte records] <---- Probably not good! >How-To-Repeat: Create a virtual machine under Parallels 9 on OSX with a virtual DVDROM (a default 'new machine' will do this) - and boot a 10.0-BETA4 or 11-CURRENT kernel. >Fix: Don't boot the virtual machine with a virtual DVDROM attached **and no media** in the drive. If you have no 'media' in the drive **remove the drive** from the Parallels virtual machine configuration - unchecking the 'Connected' box is not enough to fix the issue - you have to remove it from the virtual machine hardware list with the '-' button. I realise this is probably going to be a low priority 'bug' - but at least it's now documented incase someone else runs into the issue (I couldn't find any mention of this on the lists / search engines) >Release-Note: >Audit-Trail: >Unformatted:
