broken RTL8101E/RTL8102E support (r8169 kernel module) in linux-image-2.6.27-11-generic

[Riccardo Murri]

Binary package hint: linux-image-2.6.27-11-generic

Hello,

after the upgrade to linux-image-2.6.27-11-generic this morning, ethernet (driven by r8169.ko) has stopped working: it fails to get an address from DHCP (can not even find the server via DHCPDISCOVER). Booting back into 2.6.27-9 solves the issue.

Unloading the kernel module and reloading it with::

  modprobe r8169 debug=16

results in the following lines appearing in syslog::

Jan 29 12:38:35 abaco kernel: [ 2941.481084] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
Jan 29 12:38:35 abaco kernel: [ 2941.481123] r8169 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
Jan 29 12:38:35 abaco kernel: [ 2941.481138] r8169 0000:01:00.0: cache line size of 32 is not supported
Jan 29 12:38:35 abaco kernel: [ 2941.481152] r8169 0000:01:00.0: PCI INT A disabled
Jan 29 12:38:35 abaco kernel: [ 2941.481173] r8169: probe of 0000:01:00.0 failed with error -22

and the "eth0" interface is no longerto be seen with "ifconfig". (After boot it is there, although non-functional.)
