Description Daniel Berrange 2004-03-03 17:52:08 UTC
Description of problem:
When running XFree on a Dell D505 laptop with the 855GM chipset, the X
server process hangs upon startup shortly after activating the
graphics card. Running 'strace' on the 'X' process reveals it waiting
in the vm86old system call. If I kill the process with a signal
(pretty much any severe signal seems to do the trick eg SEGV), it
breaks out of this system call & carries on with startup & appears to
operate normally. Looking at the XFree86 logs shows 


(EE) I810(0): vm86() syscall generated signal 11.
(II) I810(0): EAX=0x00003000, EBX=0x000032e2, ECX=0x0000dc00,

before it carries on with the rest of XFree startup normally.

This seems to be the same problem reported here:
