#20523 fixed Solaris vboxusbmon can panic when using alternate filesystems => fixed in svn/6.1.x x>26 John Martin - Oracle
Description

See SR 3-26796088091 for details. This SR has restricted content so only minimal information will be copied here. The Solaris vboxusbmon module can panic when using alternate attach points, in this case /a/devices/pseudo/vboxusbmon@0:vboxusbmon. The panic stack is:

VBoxUSBMonSolarisGetInfo cannot assume the driver is attached. Since there is a single instance of this device, the suggested fix:

#20521 fixed The content of the file generated by 'make --help' in shared folder is incomplete => Fixed n SVN ppggff
Description

new version virtualbox 6.1.26 with same version addition tool installed.

step:

  1. create vm and install ubuntu 20.04 lts (also tried centos 7.9, same problem)
  2. setup a shared folder: /test
  3. create file in it:
       sudo su -
       cd /test
       make --help > x
    
  4. cat x

problem:

  • expect: full usage of make
  • result: just part of expect message, and it's not in order
#20518 fixed kernel modules being rebuilt on each linux system startup => Fixed in SVN yury_t
Description

Possibly known issue already. Happens on 'other' linux system installation, as made from VirtualBox-6.1.26-145957-Linux_amd64.run. System is slackware-CURRENT.

The root of the problem seems to be vboxdrv.sh, which is copied to /etc/rc.d/init.d, and sourced from there, and contains this stuff at line 330:

[ "$mod_dir" != "misc" ] || return

...which breaks program's logic. It needs to be:

[ "$mod_dir" = "misc" ] || return

I made this change in my installation, issue's gone.
