Hello,
When I have hci0 up and I remove my USB MSI 6970 dongle, then kernel freezes.
This is copied from the screen:
----------------------------------------------------------------------
kernel panic: fatal exception in interrupt
In interrupt handler - not syncing
EIP is at uhci_remove_pending_qhs+0x61/0xc0 [uhci_hcd]
----------------------------------------------------------------------
lsmod for usb and bluetooth things:
----------------------------------------------------------------------
hci_usb 12288 1
bluetooth 43492 1 hci_usb
usbnet 15496 0
usblp 11264 0
uhci_hcd 31116 0
usbcore 107100 6 hci_usb,usbnet,usblp,uhci_hcd
-----------------------------------------------------------------------
When I start computer, hci0 is down. I run hciconfig hci0 up.
After this I have in dmesg this:
-----------------------------------------------------------------------
drivers/usb/core/urb.c: usb_submit_urb: bogus endpoint 3-IN on
usb-0000:00:07.3-1 (bad maxpacket 0)
hci_usb_isoc_rx_submit: hci0 isoc rx submit failed urb c71c1a14 err -90
drivers/usb/core/urb.c: usb_submit_urb: bogus endpoint 3-IN on
usb-0000:00:07.3-1 (bad maxpacket 0)
hci_usb_isoc_rx_submit: hci0 isoc rx submit failed urb c71c1a14 err -90
-----------------------------------------------------------------------
I have linux Mandrake 9.2 with vanilla kernel 2.6.2.
I have VIA KT133 chipset vt82c686b.
Is this kernel or hardware bug?
Is this problem of USB or Bluetooth kernel module?
Best regards,
Pavel Ruzicka

or you don't select CONFIG_BT_HCIUSB_SCO in your kernel config.

Workaround is to make "hciconfig hci0 down" before removing USB dongle
from computer.

Hello,
today I was testing this with new kernel 2.6.3 and problem is
identical like in kernel 2.6.2.

this is a known problem with UHCI USB host controllers, but not our
problem. Alan Stern has patches and fixes for it and I think at least
with 2.6.4 this problem should be gone. See the BlueZ and USB mailing
list archives for more details.

This one is new and Todd E. Johnson looked at it, but I have no time to
investigate on this problem. The only solution I can tell you is to
disable CONFIG_BT_HCIUSB_SCO.

Try 2.6.3. Maybe it is already fixed.
> Is this kernel or hardware bug?
It's a kernel problem.
> Is this problem of USB or Bluetooth kernel module?
I am quite sure that this is an USB problem.
