Loading module ath_pci on a ultra sparc 5 freezes the system. ath_hal loads correctly.

Some info about the pci card:

D-Link DWL-G520

HW ver B2

FW ver 3.1.6

Info about Atheros and wlan driver:


wlan: (Atheros/multi-bss)

ath_rate_sample: 1.2

ath_pci: (Atheros/multi-bss)

Info about linux system:

  • version set to trunk.

I don't think this will cure your problem, nevertheless it would be good if you could retry with the latest revision of the madwifi-ng code (r1378 as of this writing).

Is there something similar like a kernel oops facility available on Ultra Sparcs? If so, please provide that.

I'm having the same problem on my u5, just hardlocks when loading ath_pci. Madwifi snapshot r1416, kernel, gcc-3.4.5, binutils-2.16.1. Card is a DWL-G510 rev. B1 (AR5215). Just ring my bell in anything you want to test.

Maybe it gives some additional hints if you try to insmod ath_pci with option ath_debug=0xffffffff. Would be really helpful if you could (hand)copy&paste the lines from the output here.

Managed to get some info in single-user mode:

(none) / # modprobe ath_pci ath_debug=0xffff ath_hal: (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413, RF5413, REGOPS_FUNC, DFS) wlan: (Atheros/multi-bss) ath_rate_sample: 1.2 ath_pci: (Atheros/multi-bss) ath_attach: devid 0x1a

any updates on this issue?

Cheers :)

I have the same problem. I offer my help with debug info, tester..

04/29/06 17:36:29 changed by dyqith

From an earlier post, please try these steps:

Run under console mode (to see the kernel panics/oops) Make sure none of the modules of madwifi is loaded ath_pci should load with "option ath_debug=0xffffffff" modprobe ath_pci (if no modprobe, load the modules in order of: ath_hal, ath_rate_sample, ath_pci, wlan, wlan_scan_sta, wlan_scan_ap)

If the kernel oops have the ksyms available, it'll be easier to debug.

Can someone try it with the latest svn revision and report back ?

05/10/06 17:02:47 changed by

Same hardlock as usual with r1545.

05/10/06 18:10:02 changed by dyqith

rastejante and gustavoz, are you both using sparc also or some other arch ?

There was a ticket that said sparc hal was messed up ?

05/10/06 18:49:17 changed by anonymous

An ultra 5 (sparc64) in my case. All ultra machines are basically sparc64. Gentoo is currently using gcc-3.4.x for the stable toolchain, there were some ABI changes for sparc that are documented here There's ticket #493 about the hal issues, problem is some distributions could use different gcc versions. 4.0.x won't break if built with 3.4.x, i have to check on 4.1.x but i don't think it'll break either, but 4.1.x is known to make bad code for sparc so it would be wise to stay far away for the time being. I could throw the card in a 280R but i doubt it'll help, and i don't know if madwifi-ng is pci domain aware.

i have the same problem under suse linux 10.1...x86 arch. i tried to get what does this problem. i dont know if its exactly the madwifi. sometimes it works and sometimes it freezes the system. maybe it has to do with acpi or something. no clue. i use the svn version from just now :)
