Well, I had to boot this machine today after experimenting with vmware: I
couldn't remove the vmnet module because it was busy (for whatever
reason), I couldn't ifconfig the virtual network down and all ifconfigs
went into 'D' state (forever), similarly to few other processes (namely
sendmail, if it had worked I wouldn't have had to boot). Kernel 2.2.14.
If there had been any way to forcibly remove a module or forcibly kill a
'D' process, I'd have had much less trouble.
