Why do you think it is a hardware bug i.e. do you have some way to validate
this? No problem with disabled HT can mean synchronization issue.
Also, if it's CPU issue (e.g. it requires special patch/workaround in
software side), then issues would be seen in random subsystems, while
problem is currently isolated in VFS/FFS layers.
