Public bug reported:
Binary package hint: wine
Distro: Kubuntu Dapper 6.06
Wine: 0.9.9-0ubuntu2 (tested also with 0.9.39 from winehq.org)
Kernel: 2.6.15-29-386 (2.6.15-29.58)
When .exe is run from FAT partition, wine process gets stuck in kernel in "D"
state and cannot be killed.
I have straced the process and it appears it is stuck in:
ioctl(9, TUNIOCGETINFO or VFAT_IOCTL_READDIR_BOTH
This way user can prevent unmounting FAT partition by running wine on
FAT partition.
To reproduce:
1. Mount any FAT volume (for example USB pendrive)
2. Copy some file.exe file to it.
3. Run: wine /media/mydisk/file.exe
4. Wine hangs and cannot be killed.
Possible workaround is to recompile wine with "#define VFAT_IOCTL_READDIR_BOTH"
in dlls/ntdll/directory.c commented out.
I have checked that it works.
