rm-io Followed by Multiple set-vcpu Operations Could
Cause HV Abort or ldmd Core Dump (CR 6597761)
During a single delayed reconfiguration operation, do not attempt to add CPUs to a
domain if any were previously removed during the same delayed reconfiguration.
Either cancel the existing delayed reconfiguration first (if possible), or commit it (by
rebooting the target domain), and then apply the CPU addition.
Failure to heed this restriction can, under certain circumstances, lead to the
Hypervisor returning a parse error to the LDoms Manager, resulting in the LDoms
Manager aborting. Additionally, if any VIO devices had been removed during the
same delayed reconfiguration operation, when the LDoms Manager restarts after the
abort, it will incorrectly detect the need to perform a recovery operation, resulting in
a corrupt configuration being created, and leading to a Hypervisor abort and
machine power-down.
cryptotest Intermittent SUNW_RANDOM Generate
Failure (CR 6572985)
During long test runs, SunVTS cryptotest could fail intermittently with an error
similar to the following:
Workaround: Install SunVTS Patch 127294-01.
modunload While the nxge Port is Running, Could Cause a
System Panic (CR 6551509)
If you modunload the nxge driver while it is running, the system could panic. Due
to an issue in the nxge driver, it is possible, though very unlikely, that the nxge
driver could cause a panic during a system reboot. This panic occurs if the system is
still transferring substantial amounts of network data over an nxge interface while it
is going down. It is very unlikely that this condition will occur in normal
circumstances.
The panic message would be mutex_enter: bad mutex, ... The panic stack
will include the two nxge driver functions nxge_freeb() and nxge_post_page().
If such a panic occurs, the system will recover, and continue to reboot normally. The
system, including the nxge interfaces, will come back up with no further panics.
Workaround: Unplumb the interfaces prior to unloading the driver.
