<6>usb 1-1: [ueagle-atm] (re)booting started
AFAIC, last working kernel was 2.6.18-rc5-mm1.
.config attached.
ok I found where it comes from : somebody patch ueagle-atm and broke it
:
http://www.kernel.org/git/gitweb.cgi?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=e7ccdfec087f02930c5cdc81143d4a045ae8d361
I have to investigate why this patch is need, but it is nice to see that
it wasn't forwarded to the maintainers...
Matthieu
Good catch! Here is a patch (against --mm tree) to fix that:
---
ueagle-atm: fix oops in sysfs_create_group()
The array of attribute passed to sysfs_create_group() must be
NULL-terminated.
