Ok, I followed all your instructions... But I don't think the problem is
in do_exit. I mucked up ;( I managed to completely miss an oops! My wine
stuff is running of a Win98 FAT32 partition. Heres the oops in my log,
generated about the same time wine crashed:

Do you need other info? I am new to oopses. Please give me instructions
if I have to do anything else.
Here is the FS part of my .config:
CONFIG_AUTOFS_FS=y
CONFIG_FAT_FS=y
CONFIG_MSDOS_FS=y
CONFIG_VFAT_FS=y
CONFIG_ISO9660_FS=y
CONFIG_PROC_FS=y
CONFIG_DEVPTS_FS=y
CONFIG_EXT2_FS=y
CONFIG_NFS_FS=y
CONFIG_NFSD=y
Sorry for the confusion. I somehow thought if there was an oops it would
scream at me, not hide in the log file ;)
