Bug #933
Updated by tuxillo over 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 device 1.0 on pci2 can't re-use a leaf (debug_info)! can't re-use a leaf (stats)! can't re-use a leaf (rx_int_delay)! can't re-use a leaf (tx_int_delay)! can't re-use a leaf (rx_abs_int_delay)! can't re-use a leaf (tx_abs_int_delay)! can't re-use a leaf (int_throttle_ceil)! can't re-use a leaf (rxd)! can't re-use a leaf (txd)! 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: Jan 26 19:44:26 jupiter acpi: resumed at 20080126 19:44:26 Jan 26 19:44:27 jupiter kernel: uhub0: port 1 reset failed Jan 26 19:44:27 jupiter kernel: uhub1: port 1 reset failed Jan 26 19:44:27 jupiter kernel: uhub2: port 1 reset failed Jan 26 19:44:28 jupiter kernel: uhub0: port 2 reset failed Jan 26 19:44:28 jupiter kernel: uhub1: port 2 reset failed Jan 26 19:44:28 jupiter kernel: uhub2: port 2 reset failed Jan 26 19:44:30 jupiter kernel: uhub0: port 1 reset failed Jan 26 19:44:30 jupiter kernel: uhub1: port 1 reset failed Jan 26 19:44:30 jupiter kernel: uhub2: port 1 reset failed [...] Only rebooting the machine helps.
