The module appears on the modules list after this oops, but cannot be removed, because it's claimed to be used - but there isn't any user. If you want to modprobe usb-storage, modprobe hangs. usb-storage cannot be loaded at all. BTW: Suspending and resuming has been working fine with openSuSE 10.1 The complete modules list is: notebook1:~ # lsmod Module Size Used by ohci1394 37040 0 ieee1394 102584 1 ohci1394 button 10896 0 ide_core 133936 1 ohci_hcd 23428 0 uhci_hcd 26892 0 snd_hda_intel 23060 0 snd_hda_codec 164352 1 snd_hda_intel snd_pcm 86916 2 snd_hda_intel,snd_hda_codec snd_timer 27908 1 snd_pcm snd 61188 4 snd_hda_intel,snd_hda_codec,snd_pcm,snd_timer soundcore 13792 1 snd snd_page_alloc 14472 2 snd_hda_intel,snd_pcm nls_iso8859_1 8320 0 nls_cp437 9984 0 vfat 16640 0 fat 55324 1 vfat af_packet 29320 2 ipv6 263584 18 battery 14340 0 ac 9476 0 twofish 47488 2 cryptoloop 7680 2 apparmor 55572 0 aamatch_pcre 18304 1 apparmor loop 20488 5 cryptoloop dm_mod 60184 12 usbhid 52192 0 pcmcia 40892 0 firmware_class 14080 1 pcmcia 8139too 30592 0 mii 9600 1 8139too yenta_socket 30348 1 rsrc_nonstatic 17024 1 yenta_socket ehci_hcd 34696 0 pcmcia_core 43412 3 pcmcia,yenta_socket,rsrc_nonstatic usbcore 114896 4 ohci_hcd,uhci_hcd,usbhid,ehci_hcd intel_agp 27804 1 i2c_i801 11660 0 agpgart 35528 3 intel_agp i2c_core 25216 1 i2c_i801 reiserfs 237312 6 sr_mod 20132 0 cdrom 38432 1 sr_mod edd 13892 0 fan 8964 1 sg 38044 0 ata_piix 19332 3 ahci 25860 0 libata 119188 2 ata_piix,ahci thermal 18568 1 processor 34664 1 thermal sd_mod 24576 4 scsi_mod 136712 5 sr_mod,sg,ahci,libata,sd_mod notebook1:~ #
