Dmitry, thanks!
That's awesome to see!

You'll be amused to know I used a B180 running parisc-linux (not
nearly as stable as it is today) as my desktop/workstations in 2000 or
2001 (until I was able to scrounge a C3000).

Check "SER PIM" (IIRC) output for crashes and/or force an HPMC to
collect CPU state. The stack trace from that should give good clues
were the hang is. (And sorry, I'm forgetting if B180 has an HPMC
button on the back or not)

You can also check the "LED Error Codes" as described in:

Note that's for HPUX in some cases: we tried to follow some of the
same codes for parisc-linux but PDC will still set the LEDs when CPU
control is "handed" to PDC (ie HPMC or panic).

Helge is right. I don't think sysv init has anything to do with web
browsing performance. The C8000 probably is using frame buffer for
graphics and no acceleration. I have no idea if the Sun Blade 150 is
using HW accelaration. "glxinfo" or other commands should be able to
tell you.

In general, for computation intensive (e.g. SpecFP or SpecInt or
kernel compile), I would expect the C8000 to be at least 2x faster.
