[Debian-eeepc-devel] Bug#538410: atl1c: ethernet broken on Eee PC model 1005HA-H

[Ben Armstrong]

Package: linux-image-2.6.30-1-686
Version: 2.6.30-3
Severity: normal

When using a debian-installer daily image on an Eee PC model 1005HA-H, to which
Otavio just added atl1c, our tester, Yoda-BZH on irc, could not get ethernet to
work at all.  Here is his report:

	> debian-installer/i386/linux vga=771 initrd=debian-installer/i386/initrd.gz -- quiet

	Choosing language French
	Country: France
	KB Layout: Françs (fr-latin9)

	At this point I have few lines about atl1c in dmesg :
	atl1c 0000:01:00.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19
	atl1c 0000:01:00.0: setting latency timer to 64
	atl1c 0000:01:00.0: PME# disabled
	atl1c 0000:01:00.0: PME# disabled
	atl1c 0000:01:00.0: version 1.0.0.1-NAPI


	** detecting hardware step
	In dmesg I now have :
	atl1c 0000:01:00.0: irq 27 for MSI/MSI-X
	atl1c 0000:01:00.0: alt1c: eth0 NIC Link is Up<100 Mbps Full Duplex>
	atl1c 0000:01:00.0: Unable to allocate MSI interrupt Error: -22
	ADDRCONF(NETDEV_UP): eth0: link is not ready

At this point, dhcp fails to acquire an address.  Statically configuring the
network doesn't help, either.

Searching Linus's git tree reveals that there have been some patches to atl1c
since 2.6.30 was released, but we don't know if any of these are relevant to
our problem or not:

http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git&a=search&h=HEAD&st=commit&s=atl1c

I find it annoying that at least this bug appears to be a duplicate of an atl1e
bug fixed a year ago:

In atl1c this year, after 2.6.30 was released:

atl1c: WAKE_MCAST tested twice, not WAKE_UCAST

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0ed586d075ef65c0268982e5b7f36d0ffaa95547

In atl1e last year, submitted by the same upstream author!

atl1e: WAKE_MCAST 2x. 1st WAKE_UCAST?

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=1a3c4bc61547e5a75fd3b85b425624756da4cffb

Do you need any more info to patch 2.6.30's atl1c for us?  We'd like to get
ethernet working on this model as soon as possible.

Thanks,
