No hurries, in fact I was gathering a bit more info about this behavior. I dumped the ed_rm_list when it is hung, and we have only one element that's unkillable: [ 1108.841482] ohci_hcd 0000:00:04.0: ed_rm_list, ed ffff8800c781f140 state 0x1 type bulk; next ed 00000000 [ 1108.841489] ohci_hcd 0000:00:04.0: info 08405103 MAX=64 DQ SKIP EP=2-IN DEV=3 [ 1108.841494] ohci_hcd 0000:00:04.0: tds: head c78261e0 DATA0 tail c78261e0 (not listing) Also, there's only one non-empty ed_rm_list "pass" after the finish_unlinks between SR intr disables, when not hung. -- Tomas J.
