From your logs, the problems you encounter are part of the SCSI stack --
the sg driver to be specific. Try running on the most recent 2.6.17-rc
kernel, and post your findings to [EMAIL PROTECTED] Maybe CC:
linux-usb-devel also.
Indeed 2.6.17-rc3 seems to solve the problem (some 150+ insert/remove
cycles under different usb load conditions done ok).
I didn't realize that soo many things changed in the scsi layer
around scsi_done and friends in the 2.6.17 tree...
Thanks for the pointer and sorry for the noise.
