usb-storage on SMP?

[Thomas Zehetbauer]

Hi,

can anyone confirm that writing to usb-storage devices is working on SMP
systems? Especially to a SD Card in an USB 1.1 card reader attached to a
64-bit Dual Opteron with NUMA enabled?

I have a noname USB 1.1 card reader that identifies itself as 0dda:0001
'Integrated Circuit Solution, Inc.' attached to a Tyan Thunder K8W
(S2885) dual Opteron NUMA system. After copying data to the disk, the
activity light flashes for some time and the following messages appear
in syslog:

2005-01-15 13:41:39 +0100 kernel: ohci_hcd 0000:03:00.1: urb 0000010068400d40 path 1 ep2out 6fce0000 cc 6 --> status -71

2005-01-15 13:43:15 +0100 kernel: Buffer I/O error on device sdc, logical block 147093

The system behaves as expected if I boot the kernel with 'maxcpus=1'.

Experience is what you get when you expected something else.
