Unfortunately, it takes forever on this machine to compile a kernel after any bigger changes. I can do it early next week when I have access to my bigger box again. On the other hand, it should be easily reproducible by anyone else with the same trick, here's what I do: * configure X to use /dev/input/event* devices * in an xterm, do something like rmmod usbhid ; modprobe usbhid * switch to a VT * watch kernel crash as X releases the grab on the event device Mind you, I actually did this with the appletouch driver, but I don't think it makes a difference since the problematic thing is the code that X grabs the device. A trivial program that executes the grab ioctl would probably suffice if you leave it running over a rmmod/modprobe cycle. johannes --=-aXF4e4I+WnOwyR7EhsWr Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIVAwUAR+1t4qVg1VMiehFYAQIyVA//YCg2FLSChFspD/yc2Qw/7VHT0+4x34Hx Y/ZjriGYJzH94H3eZfS/Vsi8I5fsthSFp7KQeuwaA3dO3dQt1vJipjuB6frPAf8/ uE2MvnleDv0nLcq9wXY7pYGVT4GZzvym0gmdoASoVnNvdEtlRpZpOo45uXAJfD1q ++1AIdGoRwEBUHphGl+Q4lwRl6bcwZhxbeBl2cgpAyjDbqHav9tQAP21z9AxNcYl gADGE2yAou0/a/tXinv63MM0f/HkwCl6Vdo/vRYWTgWvLPTBFQSFfFZPTZ7Dxwq4 5vYhJb0wXndQQLMz/B5BU/fn0Pb2y40/uhpheL62Hbppu/jLM3G2uBFlcxd1Vure a4nn8I04/5Dsk4CdpnkB5+ntx+8d2Jat661EYxBiQ+lXJdVoENlUKTyVJykcFyxG 8ba3GfaASTeZ2S02T6lE1TBGaKlGEp9ujb47v1o05hYunKaONFrDV4Lt1Zmyf++7 nYjm/asWdYb4wep/sKBKb708js+lbL707Y8xa2v7YAiuCvz76pqiCH6nnaJrAtqg B2lqPnKnt0DDTl1y+9cWEEIR2Z4k7rLNd3NczGoZ/q5hfe2QrX19Wk4t0EgK4gy9 Hk4JCJmMYQxdB0djoDu4iP4mPvqJVAzqaLjPuOrQ1qa6inIVFtsl+B91HBD1J7/3 XvTrGye1mV4= =bQFa -----END PGP SIGNATURE----- --=-aXF4e4I+WnOwyR7EhsWr-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
