2.6.20-rc4 sky2 unsupported chip type 0xff / phy write timeout

[Florian Lohoff <flo@rfc822.org>]

Hi,
i have random problems after fresh boot with the onboard sky2 on an
Fujitsu Siemens Lifebook E8110. With 2.6.18-686-3 from the Debian repository i see
random crashes on boot - see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=404107

With a 

	Linux machine 2.6.20-rc4 #0 SMP PREEMPT Mon Jan 8 15:18:15 CET 2007 i686 GNU/Linux

i dont see crashes now but instead i see on random boots:

	[   12.412000] ACPI: PCI Interrupt 0000:02:00.0[A] -> GSI 16 (level, low) -> IRQ 16
	[   12.412000] PCI: Setting latency timer of device 0000:02:00.0 to 64
	[   12.412000] sky2 v1.10 addr 0xf0000000 irq 16 Yukon-EC Ultra (0xb4) rev 2
	[   12.412000] sky2 eth0: addr 00:17:42:13:45:8c
	[   24.548000] sky2 eth1: enabling interface
	[   24.552000] sky2 eth1: phy write timeout
	[   24.556000] sky2 eth1: phy write timeout
	[   24.556000] sky2 eth1: phy write timeout
	[   24.560000] sky2 eth1: phy write timeout
	[   24.560000] sky2 eth1: phy write timeout
	[   24.564000] sky2 eth1: phy write timeout
	[   24.564000] sky2 eth1: phy write timeout
	[   24.568000] sky2 eth1: phy write timeout
	[   24.568000] sky2 eth1: phy write timeout
	[   24.572000] sky2 eth1: phy write timeout
	[   24.572000] sky2 eth1: ram buffer 1020K

Afterwards the interface is not usable as one would have expected. rmmod/modprobe later:

	[  186.536000] sky2 eth1: disabling interface
	[  186.536000] sky2 eth1: phy write timeout
	[  186.564000] ACPI: PCI interrupt for device 0000:02:00.0 disabled
	[  190.464000] PCI: Enabling device 0000:02:00.0 (0000 -> 0003)
	[  190.464000] ACPI: PCI Interrupt 0000:02:00.0[A] -> GSI 16 (level, low) -> IRQ 16
	[  190.464000] PCI: Setting latency timer of device 0000:02:00.0 to 64
	[  190.464000] sky2 0000:02:00.0: unsupported chip type 0xff
	[  190.464000] ACPI: PCI interrupt for device 0000:02:00.0 disabled
	[  190.464000] sky2: probe of 0000:02:00.0 failed with error -95

On a working boot i see:

	[   12.236000] ACPI: PCI Interrupt 0000:02:00.0[A] -> GSI 16 (level, low) -> IRQ 16
	[   12.236000] PCI: Setting latency timer of device 0000:02:00.0 to 64

	[   24.552000] sky2 eth1: enabling interface
	[   24.556000] sky2 eth1: ram buffer 0K
	[   26.200000] sky2 eth1: Link is up at 100 Mbps, full duplex, flow control none
