[Bug 38238] Re: prism54 no longer works

[Albrecht Gebhardt]

*** This bug is a duplicate of bug 38278 ***

same problem for me (old NetGear WG511 pre ver3).

lsmod shows that both prism54 (old fullmac driver, KERNELSRC/drivers/net/wireless/prism54) AND islsm* (new softmac driver, KERNELSRC/drivers/net/wireless/prism54_softmac) are loaded. unfortunately islsm_pci tries  wins and tries first to upload its firmware.

lsmod
Module                  Size  Used by
prism54                59688  0
islsm_pci              24488  0
islsm_device           12584  1 islsm_pci
islsm                  40172  2 islsm_pci,islsm_device
ieee80211softmac       30272  1 islsm
crc_ccitt               2240  1 islsm

the first "ifconfig ethX up" tries to load the (rong) firmware:

[4322194.635000] islusb: Request firmware for 'isl3886' failed: -2
[4322194.636000] eth2: could not upload firmware ('isl3886')
[4322194.636000] eth2: islpci_reset: failure
[4322194.686000] islusb: unable to boot device


But when I first (before "ifconfig ethX up") rmmod all islsm* and the prism54 module and then re-insert only the prism54 module it starts working again:

<insert card>
rmmod islsm_pci
rmmod islsm_device
rmmod islsm
rmmod prism54
modprobe prism54
... works:
dmesg
...
[4321395.167000] Unloaded islsm_pci driver
[4321418.036000] Unloaded prism54 driver
[4321426.859000] Loaded prism54 driver, version 1.2
[4321426.860000] ACPI: PCI Interrupt 0000:02:00.0[A] -> Link [LNKA] -> GSI 11 (level, low) -> IRQ 11

[4321427.012000] eth2: firmware version: 1.0.4.3
[4321427.012000] eth2: firmware upload complete

So if someone knows how to "blacklist" the islsm_pci driver for the old prism54 cards, this could help ... 

Best regards

Albrecht
