Hello,
I have seen a very strange deadlock on a UltraSPARC 2 workstation (2
UltraSPARC-II/296 MHz, 2048 MB, framebuffer Creator3D on UPA slot, 2 73
GB SCA disks that form a raid1 array).
Hardware sounds good and I have tested it with SUNvts during two days
without any failure.
This workstation is a mail server and runs with Debian/testing, kernel
2.6.20. It's a NIS and NFSv3/TCP clients. Its uptime was more than 9
days and it hangs without any message in the log, without panic and
without oops. When it hangs, the queue of sendmail was about 3 GB due to
a failure of a internet peering. I have rebooted the workstation (power
button :-( ). You can find my .config at
http://rayleigh.systella.fr/~bertrand/config-sun4u-2.6.20.gz
I don't know how debug this bug...
Regards,
JKB
