| |
Hello again,
>>>Yep, look @ http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/airo-linux/airo-linux/kernel/
I've now installed this driver and it has had no effect. VNC still causes this lockup readily. The symptoms are the same: alt-sysrq works, but the keyboard is frozen. I can sync disks, but I can't reboot.
Hopefully this report will be better than the last; I'm running vanilla kernel 2.4.21-pre5 with the 'badram', 'debianlogo', 'lowlatency', and 'preempt' patches. My previous report of apparent success with the aux_bap=1 setting was flawed. It failed as well.
The OOPS generally looks like this: airo: BAP error 4000 2 Warning: kfree_skb passed an skb still on a list (from d0acb466) kernel BUG at skbuff.c:315! invalid operand: 0000 [...] Call Trace: [<d0acb466>] [<d0acb466>] [<c011d117>] [<c0105550>]
rebooting and running 'ksyms' for each of these gives:
d0ac8060: __insmod_airo_S.text_L43104 d0acb466 d0acba20: stop_airo_card
but nothing for the c0* addresses. Further info is that I am using a Cisco 350 PCMCIA (PC-104/ISA) wireless card with the TxPower set to 20mW (14dB) and no encryption; running in managed mode.
I am also now subscribed to the LKML so I can see replies. I've been told that the 2.4.19 driver works with 2.4.20 so I may try that next. That or the Cisco driver ...
Thanks for any help, and please Cc: me directly. Christopher
