[Bug 255465] Kernel panic with Intel Wireless 4965AGN chip
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=255465 --- Comment #2 from Radosław Chmielarz --- Hi, Sorry for this, it seems I forgot to add it. I was looking into the code to figure out where the problem is originating from and the actual problem turned out to be that I was getting "timeout reading ROM" error messages at startup, this in turn was causing all the values to be 0 and since the code in ieee80211_get_ratetable() (called from ieee80211_chan_init()) assumed that the channel value passed in was valid it was calling panic() to indicate that there is missing implementation for this device. I have then drilled down to the code which was reading EEPROM and compared it with Linux (where the device is working). I had not seen any significant differences apart from a different timeout handling. After modifying the timeout the device was successfully initiated. I own an Intel 4965AGN MM2 with TA: D74676-004 and the measured EEPROM read time for it with 5 us delay is 60 us and with 1 us delay 25 us. This is larger than what the current code supports. It's also strange since the code is already several years old and this particular chip is quite popular (at least from what I have read). Either this is specific to my hardware setup or the hardware is not used so often. I will post a separate email with a patch for adjusted read timeout and timeout error handling. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-wireless@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "freebsd-wireless-unsubscr...@freebsd.org"
