https://bugzilla.kernel.org/show_bug.cgi?id=25832 --- Comment #82 from rocko <rockorequin@xxxxxxxxxxx> 2011-05-26 06:44:12 --- I just hit this again in 2.6.39. I was trying to delete a partition from an external drive, something went wrong and for some reason the kernel dumped all the other attached USB drives, whereupon the entire machine crashed with an "unable to handle paging" then "scheduling while atomic" oops. It's a really annoying bug. This is what was recorded in the system log (it actually got written this time): May 26 14:28:02 hercules kernel: [128626.171297] xhci_hcd 0000:04:00.0: WARN: Stalled endpoint May 26 14:29:36 hercules kernel: [128720.267229] xhci_hcd 0000:04:00.0: WARN: Stalled endpoint May 26 14:29:36 hercules kernel: [128720.353640] xhci_hcd 0000:04:00.0: WARN: Stalled endpoint May 26 14:29:36 hercules kernel: [128720.380617] xhci_hcd 0000:04:00.0: WARN: Stalled endpoint May 26 14:29:41 hercules kernel: [128725.194501] xhci_hcd 0000:04:00.0: WARN: Stalled endpoint May 26 14:29:41 hercules kernel: [128725.222284] xhci_hcd 0000:04:00.0: WARN: Stalled endpoint May 26 14:29:46 hercules kernel: [128729.766858] xhci_hcd 0000:04:00.0: WARN: Stalled endpoint May 26 14:29:46 hercules kernel: [128729.801933] xhci_hcd 0000:04:00.0: WARN: Stalled endpoint May 26 14:29:53 hercules kernel: [128736.817629] xhci_hcd 0000:04:00.0: WARN: Stalled endpoint May 26 14:29:53 hercules kernel: [128736.817863] xhci_hcd 0000:04:00.0: ERROR no room on ep ring May 26 14:29:53 hercules kernel: [128736.817873] xhci_hcd 0000:04:00.0: ERR: No room for command on command ring May 26 14:29:53 hercules kernel: [128736.817882] xhci_hcd 0000:04:00.0: FIXME allocate a new ring segment May 26 14:30:00 hercules kernel: [128743.863985] xhci_hcd 0000:04:00.0: ERROR no room on ep ring May 26 14:30:00 hercules kernel: [128743.863998] xhci_hcd 0000:04:00.0: ERR: No room for command on command ring May 26 14:30:05 hercules kernel: [128748.872230] xhci_hcd 0000:04:00.0: xHCI host not responding to stop endpoint command.
