How are you supposed to disconnect a port multiplier without causing the kernel to go into error recovery because the link went dead and the device vanished? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBCgAGBQJTUH2TAAoJEI5FoCIzSKrwhksH/0whe5rWffNrj+aZY+u+o4tQ tvNhCNStgxAK6hKi2higHSVHQbO12Vk1JgfNkp0IRDineMkBdGnb3gGFGxgP00V2 onKcPjIgmTL/0zlMx+MJHZRR3nh+6SkbJhdB2dqCDN1l5i4G9Je2lK2hIxs6DYZN zy7vFL2ftvSPIWC8Z/zVZIYhfiGHp7LoVxVAKSFJaPuU7MhHqdHihlUbaCBPMRJs YquXAg5euJ98WXSDfqG21hWJgT7L6UnQwV21MnsCuI3euAk83MKQFYClNhewu5kp C02WdWLrxNjc32bink/kPCHRgjgCC58YHG4zKxRNlOUFCYERVJk4IR9FeCTt3tw= =qvds -----END PGP SIGNATURE-----
