Bug#433629: gcc-4.2: breaks linux kernel usbhid
Package: gcc-4.2
Version: 4.2-20070707-1
Severity: normal
On Monday ("Mon Jul 16 10:39:51 2007"), I compiled the linux kernel
version 2.6.22+git-e904e31ddef89e03f9f45f255a63803dbe708645
(that's a version from the wireless-dev tree on git.kernel.org) and
used it until today. According to the dpkg log, I upgraded my gcc
later yesterday:
2007-07-16 19:14:07 upgrade gcc-4.2 4.2-20070707-1 4.2-20070712-1
Today then, I wanted to compile a new kernel later git and USB HID
stopped working. Thinking that the problem lies in the kernel I
started to bisect only to find that the problem is not in the kernel,
in fact using the same sources I compiled yesterday morning don't
work with gcc-4.2-20070712-1.
Going back to gcc-4.2-20070707-1 however didn't make it work again
so I guess that the usbhid module wasn't rebuilt with the 070707
version because I hadn't completely rebuilt the kernel, the new
compile where it started failing was a complete rebuild. For now
I've gone back to 4.1.2-13 which works perfectly with the same
sources.
I'm filing the bug against 070707 but it is well possible that
earlier versions are affected as well.
Symptoms of usbhid not working are:
* usbhid loaded before ohci-hcd: no input devices show up
* usbhid loaded after ohci-hcd: system hangs when loading usbhid
I haven't been able to debug further as my powerbook only allows
for USB input devices.
