Second, I'm once again enountering problems with launch the UML instance. It

Checking that ptrace can change system call numbers...OK
Checking syscall emulation patch for ptrace...OK
Checking advanced syscall emulation patch for ptrace...OK
Checking if syscall restart handling in host can be skipped...OK
Checking for the skas3 patch in the host:

Checking PROT_EXEC mmap in /tmp...OK
I remembered what this was about. Disable CONFIG_I8042, under -
UML-specific options
Input device support
Hardware I/O ports
i8042 PC Keyboard controller
This is a UML bug which I haven't tracked down yet.
Just for reference, that's CONFIG_SERIO_I8042 on 2.6 kernels.
I disabled that on the kernel that was giving me the same hang
point on x86_64 and.... same hang. I turned off all the other hardware
options in that menu (serial port, game port) and.... hmmm. A kernel that
was at least successfully building before is now:
CC arch/um/sys-x86_64/signal.o
arch/um/sys-x86_64/signal.c: In function 'setup_signal_stack_si':
arch/um/sys-x86_64/signal.c:171: error: invalid lvalue in assignment
make[1]: *** [arch/um/sys-x86_64/signal.o] Error 1
make: *** [arch/um/sys-x86_64] Error 2
The line in question is the ((unsigned char... :
frame = (struct rt_sigframe __user *)
round_down(stack_top - sizeof(struct rt_sigframe), 16) - 8;
((unsigned char *) frame) -= 128;
if (!access_ok(VERIFY_WRITE, fp, sizeof(struct _fpstate)))
goto out;
I'm reasonably sure this showed up because I upgraded to fc4 at
the end of last week - sorry about that.
.config attached.
Cheers,
- Bill
