various revisions of madwifi trunk - till now, did search on about 20 revisions, problem is on not manifested on revisions before 2210 and is manifested on revisions after 2235. I am still searching for revision which caused this, anyway, more ppl told me on IRC that they have crashes like this, so i am creating this ticket.
Problem could be seen on 3 machines, not been able to reproduce it on 4th one, machines are equiped with various HW, from SW point of view all are running Slackware 10.2 with lost of custom modifications, the key part is heavilly patched linux kernel 2.6.20.6 and various madwifi revisions as i have said above. There are several atheros cards in these machines, the one where crash could not be reproduced is VIA based 6PCI mobo with 9 atheros and 2 prism cards equiped, the ones where crash has been presented is VIA based mobo with 3 PCI slots equiped with 9 atheros cards - mixed CM9 and CM10 and RB52 same atheros mixture as first box, another box which crashed in serverworks based old machine with P3 600 and 2 atheros and 3 prism cards, the 3th which crashed is via based mobo with 3 PCI slots equiped with 1 atheros and 2 prism cards.
trace follows , i will update ticket when i will find something new
interesting point is, that on some boxes - there is no crash/oops message at all, machines simply lock - that is case of that VIA based machine with 1 atheros card and that serverworks based one
