I just upgraded an UltraSparc 10 from kernel 2.4 to 2.6, using the Debian package in sarge:
myriam:~ % dpkg -s kernel-image-2.6.8-1-sparc64 Package: kernel-image-2.6.8-1-sparc64 Status: install ok installed Priority: optional Section: base Installed-Size: 21560 Maintainer: Debian Kernel Team <debian-kernel@lists.debian.org> Architecture: sparc Source: kernel-image-2.6.8-sparc Version: 2.6.8-2 Now, I can no longer shutdown (it worked before): there is no error message, shutdown backgrounds itself and then is stopped in Disk Wait (I tried several times, hence the three shutdowns in ps' output). myriam:~ % ps auxwww|grep D USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.2 1632 704 ?
