>Description:
The ale(4) interface on my EeePC 900A does not detect a carrier on all
switches and speeds.
When plugged into a gigabit port on a Linksys SRW224 switch, the switch
shows a link (not full-speed of course), but ifconfig shows no carrier.
DHCP cannot get an address.
When plugged into a 10/100 port on the same Linksys switch, the connection
works.
When plugged into a cheap 10/100 switch, the link light on the switch goes
out during the kernel autoconf messages and does not recover until the
switch itself is powercycled. When connected to this switch I get the
following errors:
ale0: DMA read error ! -- resetting
ale0: could not disable Tx/Rx MAC(0x000000008)!
I'm network booting in all cases, so pxeboot is talking to the network happily.
Linux also works fine in all cases.
Device is (hand copied):
ale0 at pci3 dev 0 function 0: Attansic/Atheros L1E Ethernet
al0: AR8113 (L2E RevA), ioapic0 pin 19
atphy0 at ale0 phy 0: L1 10/100/1000 PHY, rev.9
>How-To-Repeat:
Try an Asus EeePC 900A with various switches
