Bug #933

Updated by tuxillo almost 2 years ago

He,

since today I have an IBM Thinkpad T42 here. The machine is equipped
with a em(4) NIC and a ath(4) wireless NIC. After testing ACPI suspend
to RAM (state 3) which works flawlessly, I noticed some errors right
after the resume:

device_probe_and_attach: em0 attach returned 5
em0: <Intel(R) PRO/1000 Network Connection, Version - 6.2.9> port
0x8000-0x803f mem 0xc0200000-0xc020ffff,0xc0220000-0xc023ffff irq 11 at

em0: The EEPROM Checksum Is Not Valid
em0: Unable to initialize the hardware
device_probe_and_attach: em0 attach returned 5

Why does the EEPROM checksum changes during a suspend/resume cycle? Is
it possible to suspend with this card? This error also happens if I
unload the modules right before the suspend and load it again after
resume.

An error also happens with the ath(4). If I don't unload the driver,
the card no longer gets an IP address from the DHCP server.
Loading/Unloading etc won't help.

A third error happens with USB stuff. If I don't unload the USB module
I see a continuously stream of the following messages:

Only rebooting the machine helps. Append the relevant information:
