Issue with samba and xen.



On a 10.0_BETA/amd64 system running GENERIC kernel, I can set up a samba share and successfully connect to it from windows and other machines.

If I reboot the system with xenkernel415 and XEN3_DOM0 kernel, and try to do the equivalent connection smbd dies with:

  1261   1261 smbd     CALL  writev(0xf,0x7f7fff9d6550,2)

  1261   1261 smbd     RET   writev 162/0xa2
  1261   1261 smbd     CALL  fcntl(0x12,F_SETLKW,0x7f7fff9d6700)

Same thing happens with a XEN3_DOMU system with equivalent userland setup:

   242    242 smbd     CALL  writev(3,0x7f7fff2b7f50,2)
   242    242 smbd     GIO   fd 3 wrote 494 bytes

Any ideas what's going on?
