#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:

#10745 obsolete Guru Meditation 1103 (VINF_EM_DBG_HYPER_ASSERTION), error -1701 (VERR_MM_HYPER_NO_MEMORY) John Watson
Description

Using VB 4.1.18. Host is OEL5.6 x86_64, guests are OEL5.7 x86. Not using 64bit guests because CPUs are the older AMD Opteron 248 that don't have hardware virtualization. I have told VB not to use HW virtualization, see "Hardw. virt.ext: off" in the attached showvminfo.txt file. I have three VMs: oel57net has 500M RAM, this never fails. It doesn't do much: acts as a DHCP and DNS and NFS server for the other two. oel57a and oel57b have 1500M RAM and fail regularly but unpredictably with a Guru Mediatation 1103. They never last more 15 minutes, they usually last at least 5 minutes. I had thought that the problem was to do with the software I am running (I'm building a Oracle 11.2 cluster) but I do not believe this: the failures sometimes occur before starting the clusterware daemons. I previously raised this issue on the forum when I was using VB release 4.1.12 this is the link tio the post https://forums.virtualbox.org/viewtopic.php?f=7&t=49184&p=223700&hilit=guru+meditation+1103#p223700 which includes more examples of the problem. Please tell me any other information I can provide, and thank you for any assistance.
