** Summary changed:
- Regression: b44 Broadcom Ethernet stopped working
+ b44 Broadcom Ethernet stops working after installation of backports modules
** Description changed:
- Binary package hint: linux-image-2.6.27-7-generic
+ Binary package hint: linux-backports-modules-2.6.27-7-generic
- With the latest 2.6.27-7-generic kernel
(linux-image-2.6.27-7-generic_2.6.27-7.13_i386.deb) my onboard ethernet doesn't
work anymore. The problem wasn't present with one of the earlier 2.6.27-7
kernels. I didn't reboot for several days, so I can't tell for sure which
update introduced the bug.
- Older kernel versions work fine.
+ My onboard ethernet works fine with the latest kernel.
+ With the backports modules installed, however, this isn't the case.
