At the same time this appeared in the syslog: Aug 7 17:19:57 tibook kernel: Unhandled interrupt 1d, disabled=20 Plugging the mouse to the other socket worked, but it wouldn't work again in the original one. As you can see in the attached /proc/interrupts, interrupt 29 (=3D1d) is unknown. Interestingly, interrupt 28 seems to be for the USB socket which stopped working (I think it was the same one when the first problem first occured, might be coincidence though). Was it somehow rewarded for its 100'000th occurence? ;) Seriously, is it possible that the number changed somehow? This wouldn't be all that bad, if the whole system wasn't very sluggish afterwards. When it occured the first time, I had CONFIG_TAU enabled in the kernel, which Ben said might cause the sluggishness at least. But now it's disabled. This is on a TiBook III/667 running 2.4.18-ben0-lotsanicestuff if it matters. The first occurence was with 2.4.19-presomething-ben0. Has anyone experienced anything similar? --=20 Earthling Michel D=E4nzer (MrCooper)/ Debian GNU/Linux (powerpc) developer XFree86 and DRI project member / CS student, Free Software enthusiast --=-ucK6nKLzBlp2Y33RYoYr Content-Disposition: attachment; filename=interrupts.BAD Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; name=interrupts.BAD; charset=ISO-8859-1 CPU0 =20 1: 1908 OpenPIC Edge Built-in Sound out 2: 0 OpenPIC Edge Built-in Sound in 19: 132189 OpenPIC Level ide0 20: 51 OpenPIC Level ide1 25: 1557896 OpenPIC Level VIA-PMU 26: 226 OpenPIC Level keywest i2c 27: 33611 OpenPIC Level usb-ohci 28: 108865 OpenPIC Level usb-ohci 41: 1800835 OpenPIC Level eth0 42: 0 OpenPIC Level keywest i2c 47: 398650 OpenPIC Level GPIO1/ADB 55: 0 OpenPIC Edge NMI - XMON 57: 19 OpenPIC Level Airport 61: 1 OpenPIC Edge Headphone detect BAD: 1 --=-ucK6nKLzBlp2Y33RYoYr-- ** Sent via the linuxppc-dev mail list.
