After upgrading a server with diskless clients of more than one SPARC kernel architecture, such as a sun4u server with diskless sun4c, sun4d, and sun4m clients, the SUNWkvm packages for clients whose kernel architectures differ from that of the server cannot be patched.
Workaround: Manually add all of the SUNWkvm packages before applying any patches that affect them.
# pkgadd -d SUNWkvm.*
The upgrade program can exaggerate by as much as 30 percent the amount of space required for upgrades to systems with the Solaris software. Therefore, it prevents many systems from being upgraded without deselecting packages or finding more space.
Workaround: You can manually reallocate disk space among file systems or use the Software Customization menu to remove software packages that are not needed.
After upgrading an x86 machine with the Etherlink XL Ethernet chip to the Solaris 7 3/99 operating environment, the machine may lose network connectivity and display the following error message when booting:

elx "pci10b7,9000"elx "pci10b7,9050"
