Testing 2.6.15-rc4
Hi,
Recently I have tested the new kernel on my Ultra 10. Here is a short
summary of my observations:
1) Parallel port (parport_pc) works. I noticed that FIFO/DMA was
disabled by default. With FIFO/DMA enabled I experienced some problems
with previous kernel versions (oopses or complete lockup).
# CONFIG_PARPORT_PC_FIFO is not set
2) snd-sun-cs4231 works
3) snd-ens1371 works
The machine is very stable. I'm running apache, exim4 and Arno's
iptables firewall.
I must mention that I recompiled iptables from source because of some
"Invalid argument" messages.
The only remaining problem is the unstability of the bttv driver under
SPARC (complete lockup after approx. 15-20 min). I tried just about
every possible settings but until now without success. The strange
thing is that the same card (Jetway bt878) works fine under Solaris
with the bt848x driver, so hardware problems are out of question. Here
are some error messages
