[Bluez-users] Disconnect errors on 2.6.18-mh7

[Bluez-users] Disconnect errors on 2.6.18-mh7

[Paul LeoNerd Evans]

[-- Attachment #1.1: Type: text/plain, Size: 930 bytes --]

I've got a custom-built 2.6.18 patched with mh7 on my desktop machine,
with a Logitech Cordless Elite Blutooth Keyboard and Mouse combo. Up
until 2.6.16 these worked fine. 2.6.17 has unrelated-to-bluez issues with
my graphics card. On 2.6.18, I can connect the keyboard/mouse on startup,
but if I let them idle too long, they disconnect in an unrecoverable way,
requiring me to ssh from another box and run "hidd --search" while
simultaneously pressing the "connect" button on the keyboard or mouse.

I'm not sure quite when it happens, but it would seem to be related to
lines of the following occuring in dmesg:

net/bluetooth/hidp/hid.c: event field not found

Is this a bug that's crept in to 2.6.18, or perhaps a hardware issue, or
what? Anything I can attempt to debug it with?

run "hcidump -X -V" and show us the result for the disconnect phase and
the failed attempt to re-connect.

Well, I recently rebooted the kernel, to try out something else. Since
then (Monday), I've not actually noticed a single failing disconnect,
despite me leaving it alone during the day, overnight, and so on. I
suspect it was a transient error somehow in the previous boot of this
kernel.

I'll leave the hcidump running anyway, it's writing a logfile now, and if
it happens to start doing this again, I'll take a look.
