Message-Id: <4176CBBD.8080909@free.fr> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: sparclinux@vger.kernel.org Hi, we have tried to run 2.6.x series on 2 sparc64 machines. The first one is a 4 CPU sun enterprise [1] . With the 2.6.x the maximum uptime was 11 day, after that the machine freezed with no error message (we even tried with netconsole). With this machine we have tried vanilla kernel 2.6.3->2.6.8 with no result since mars 2004. The 2.4 series seems to work well. On the second machine [2], we only try Debian kernel-image-2.6.8-1-sparc64 . The machine hangs randomly. The machine hangs when loading snd-ioctl32. Also there is a minor problem with mouse working only after unplugging repluggin. Also we notice on recent 2.6 kernel (2.6.8 for example) that if the machine is cut from the nfs server, the machine freezes. It isn't happen on 2.4 kernels. If someone is interested in making work 2.6 kernel on these old machines, we could provide other informations.
