I applied Oliver & Alan Cox's patches to the 2.4.24 kernel, and am still seeing hangs when copying large amounts of data over USB on IBM systems containing two EHCI controllers (Intel 82801EB). I see similar errors to the ones Lucas Postupa had in the kernel logs : Buffer I/O error on device sda1, logical block 134522 lost page write due to I/O error on sda1 Unloading the EHCI driver, and reverting to 1.1 speeds, does not solve the issue. - -Martin -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) iD8DBQFAF+7vgZQNxll+EIcRAtkKAJ476IhZ+fLcyj73mDjNptU3rWmQ/ACeIIpz M5S8ast+WlfEHhKrbAtuPg0= =NH9l -----END PGP SIGNATURE-----
