wineserver hitting kernel bug?

[André Hentschel]

Hi all,
i get
  err:process:start_wineboot failed to start wineboot, err 1359
which of course leads to major problems, i tracked it down to server/process.c
in function process_poll_event it hits the line
  if (event & (POLLERR | POLLHUP)) kill_process( process, 0 )
because event is 0x19

what can cause that? maybe a kernelbug?
that's with ext3 and after working around https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/697004/
yes, it is on ARM (pandaboard)
uname -a :
Linux panda 2.6.35-903-omap4 #19-Ubuntu SMP PREEMPT Wed Nov 17 16:11:04 UTC 2010 armv7l GNU/Linux

FWIW, I get the same on powerpc:

austin@gcc40:~$ WINEDEBUG=+process,+wineboot ./wine-git/wine

and it just hangs there, using 100% cpu, never timing out.

That error seems to be a regression, at least on powerpc64, introduced by:

Note that this is a 64-bit machine, but wine was compiled as 32-bit:

That said, wineboot also hangs before this commit.

No, the most likely reason is that the process crashed. Try strace or
gdb.
