I have tried 2.6.x kernels before with no luck (hanging on resume). Today I tried 2.6.6-rc2-mm1 and it works :) It works from X too. I'm running Debian GNU/Linux with mixed testing/unstable setup. The method I use to put the machine to sleep is: echo 3 > /proc/acpi/sleep I have not tried USB after resuming, but I suspect it does not work because of an kernel oops i get: Unable to handle kernel NULL pointer dereference at virtual address 00000000 printing eip: c01b9a9b *pde = 00000000 Oops: 0000 [#1] PREEMPT CPU: 0 EIP: 0060:[get_kobj_path_length+26/49] Not tainted VLI EFLAGS: 00010246 (2.6.6-rc2-mm1) EIP is at get_kobj_path_length+0x1a/0x31 eax: 00000000 ebx: 00000000 ecx: ffffffff edx: c5f35738 esi: 00000001 edi: 00000000 ebp: ffffffff esp: c5f81dfc ds: 007b es: 007b ss: 0068 Process khubd (pid: 493, threadinfo=c5f80000 task=def871b0) Stack: 0000010c c5ad4019 c5ad4000 c3eb9200 c01b9c55 c03444c0 c5f35738 0000010c e1982460 c015af17 c5f81e3c c5ad4000 00000000 c030ba20 e197f143 00000000 c0162b2a c5f35738 c5f35730 e1982400 e1982460 c01b9de3 c02daa76 c03444c0 Call Trace: [kset_hotplug+340/653] kset_hotplug+0x154/0x28d [lookup_hash+31/35] lookup_hash+0x1f/0x23 [dput+34/616] dput+0x22/0x268 [kobject_hotplug+85/87] kobject_hotplug+0x55/0x57 [kobject_del+27/51] kobject_del+0x1b/0x33 [class_device_del+136/174] class_device_del+0x88/0xae [pg0+559628779/1069776896] hci_unregister_dev+0x10/0xa1 [bluetooth] [pg0+559312323/1069776896] hci_usb_disconnect+0x35/0x7e [hci_usb] [pg0+558698720/1069776896] usb_unbind_interface+0x7a/0x7c [usbcore] [device_release_driver+100/102] device_release_driver+0x64/0x66 [bus_remove_device+85/150] bus_remove_device+0x55/0x96 [device_del+93/155] device_del+0x5d/0x9b [device_unregister+19/35] device_unregister+0x13/0x23 [pg0+558723051/1069776896] usb_disable_device+0x71/0xac [usbcore] [pg0+558701501/1069776896] usb_disconnect+0x9b/0xe8 [usbcore] [pg0+558710243/1069776896] hub_port_connect_change+0x26f/0x274 [usbcore] [pg0+558708532/1069776896] hub_port_status+0x45/0xb0 [usbcore] [pg0+558711053/1069776896] hub_events+0x325/0x398 [usbcore] [pg0+558711213/1069776896] hub_thread+0x2d/0xe4 [usbcore] [ret_from_fork+6/20] ret_from_fork+0x6/0x14 [default_wake_function+0/18] default_wake_function+0x0/0x12 [pg0+558711168/1069776896] hub_thread+0x0/0xe4 [usbcore] [kernel_thread_helper+5/11] kernel_thread_helper+0x5/0xb Code: ff 85 c0 89 c3 74 e4 89 34 24 e8 19 72 fc ff eb da 55 bd ff ff ff ff 57 56 be 01 00 00 00 53 31 db 8b 54 24 18 8b 3a 89 e9 89 d8 ae f7 d1 49 8b 52 24 8d 74 31 01 85 d2 75 ea 5b 89 f0 5e 5f Is this ACPI relevant or should I ask the usb people?
