Do you have any idea what could it be? Original message is here: http://marc.info/?l=linux-wireless&m=122522165719760&w=2This probably is a result of the fact that we don't include firmware blobs into modular drivers any more. Please try to compile your driver directly into the kernel and enable CONFIG_FIRMWARE_IN_KERNEL. If this helps, we'll know what the problem is.Ehh ... you miss the point. The problem is NOT missing firmware (I have already been running with external firmware just fine in 2.6.27). The problem is that during resume instead of simply resume *existing* device/driver instance PCMCIA suddenly decides to re-discover the *same* device yet another again. bisecting will take ages here. I need some advice which options to turn on.I attempted to bisect, but ran into problems. As an alternative, I added a WARN_ON(err) immediately after the request_firmware call to get a stack dump: orinoco_cs 0.0: firmware: requesting agere_sta_fw.bin ------------[ cut here ]------------ WARNING: at /usr/src/linux-current/wireless-testing/drivers/net/wireless/orinoco.c:495 orinoco_dl_firmware+0xbb/0x1ce [orinoco]() Modules linked in: orinoco_cs orinoco hermes_dld hermes michael_mic aty128fb snd_maestro3 [last unloaded: hermes] Pid: 22157, comm: bash Not tainted 2.6.28-rc2-wl #41 Call Trace: [<c0117a8c>] warn_on_slowpath+0x3e/0x57 [<c019578a>] release_sysfs_dirent+0x50/0x60 [<c0195b3d>] sysfs_addrm_finish+0x73/0x78 [<c0195d03>] remove_dir+0x21/0x27 [<c02a8901>] fw_dev_release+0x15/0x1d [<c022cfbe>] kobject_release+0x0/0x5 [<c022d68b>] kref_put+0x3f/0x4c [<c02a8c7d>] _request_firmware+0x176/0x1bd [<d1083381>] orinoco_dl_firmware+0xbb/0x1ce [orinoco] [<d10836d0>] orinoco_download+0x1f/0x30 [orinoco] [<d1086b39>] orinoco_init+0x63/0x4aa [orinoco] [<c0362ee8>] __dev_get_by_name+0x18/0x72 [<c03632ed>] __dev_alloc_name+0x110/0x128 [<c03660e5>] netdev_init_queue_locks+0x29/0x41 [<c03661e6>] register_netdevice+0x60/0x1d7 [<c036638c>] register_netdev+0x2f/0x3b [<d10912a0>] orinoco_cs_config+0xe1/0x174 [orinoco_cs] [<c02ecdda>] pcmcia_device_probe+0xfa/0x144 [<c0196200>] sysfs_do_create_link+0x3c/0x10f [<c02a559e>] __device_attach+0x0/0x5 [<c02a54d9>] really_probe+0x70/0xea [<c02a5596>] driver_probe_device+0x34/0x3c [<c02a4a53>] bus_for_each_drv+0x38/0x59 [<c02a55ee>] device_attach+0x4b/0x5e [<c02a559e>] __device_attach+0x0/0x5 [<c02a4c00>] bus_attach_device+0x21/0x4f [<c02a3955>] device_add+0x147/0x272 [<c02ed29b>] pcmcia_device_add+0x1ca/0x253 [<c02ed3a1>] pcmcia_card_add+0x7d/0x8a <----- ??

Hm, what exactly do you mean? Rafael
