I addded debug=0x43fff to command line, and it produces _incredible_ ammount of syslog noise... and the error goes away, probably due to changed timing :-(. I can now reliably transfer huge files: root@amd:/data/l/linux/drivers/net/wireless/iwlwifi# tcpspray -n 1 -b 10000000 hobit Transmitted 10000000 bytes in 12.388257 seconds (788.297 kbytes/s) root@amd:/data/l/linux/drivers/net/wireless/iwlwifi# tcpspray -n 1 -b 100000000 hobit Transmitted 100000000 bytes in 123.807061 seconds (788.778 kbytes/s) root@amd:/data/l/linux/drivers/net/wireless/iwlwifi# tcpspray -n 1 -b 1000000000 hobit Transmitted 1000000000 bytes in 1265.784625 seconds (771.508 kbytes/s) root@amd:/data/l/linux/drivers/net/wireless/iwlwifi# rmmod/insmod w/o debug=, and ...huh... problem is _still_ away?!
