[parisc-linux] strace locks up 2.4.22-pa14

[Joel Soete]

Hi Grant,

I am tring to track a lpr pb on my b2k and so try:
# strace -f /usr/bin/lpr foo.doc

that works;

I read your post and try so now:
# strace -f -o /var/tmp/Strace.doc /usr/bin/lpr foo.doc

and system also hang (same behaviour as) and so I toc it (which seems to
failled ; apparently because of ide-cdrom???)

I took the opportunity to unplug ide-cable's cdrom (to test various).

Then to try to obtain a relevant toc, I re-launch:
# strace -f -o /var/tmp/Strace.doc /usr/bin/lpr foo.doc

This time it works??
Is it the same for you after the reboot?
(sorry, I tried severall time strace but no more means to reproduce)

J.

PS: btw the end of my strace is:
[...]
24801 write(3, "\1lp\n", 4)             = 4
24801 read(3, "\0", 1)                  = 1
24801 close(3)                          = 0
24801 SYS_222(0, 0, 0x1, 0x2f, 0)       = -1 ENOSYS (Function not implemented)
24801 exit(0)                           = ?

And at the same time, at the serial console I got:
+ set -v
+ exec

Have you any advise about what I miss?

In trying to debug a problem with dcopserver not starting,
I tried: 
	strace -f -o /tmp/dcop.out dcopserver

This locked up the system. I could still ping the tg3 LAN (interrupts
are enabled?). But Mouse and keyboard stopped responding.
I TOC'd
>the system - but forgot to dump PIM on the way up.
Since it's a graphical console, I don't plan on copying down
all the info.  If anyone wants to see that, please let me know
which registers are of interest (IOAQ, gr02, gr26-23 are obvious).
