Hi,
In addition to the previous message it seems that:
- RFKILL switch, switching radio on, (obviously) is a precondition. But then, it only
happens shortly after switching radio on,
- it happens more frequently and faster after switching radio on when kde + firefox + xy is running
Please find attached an image of the bug. Finally I could catch a glimpse of what happens, I longued
for this quite some time.
Strangely, as stated in the previous message, this bug does only happen in conjunction at a specific
geographical position, so far it only happened there that is. How does this correlate with the designated
code at line 2076 in iwl-agn-rs.c?:
/* Sanity-check TPT calculations */
BUG_ON(window->average_tpt != ((window->success_ratio *
tbl->expected_tpt[index] + 64) / 128));
Furthermore, it seems like there was already an encounter with this bug before. Previously I had no means
of grabbing more information off it, though, so I wrote down some notes:
2010-03-20: iwl-agn-rs.c line 2076: bug
The file where I kept my note for this bug contains:
- crashed during wireless AP scan using wpa_supplicant (after RFKILL switching to on..)
- this happend right after a fresh reboot (after crashing for the same bug)
- afterwards, auth.log contained this (bad, bad where's my data gone?):

Noticed the line in the bug from 2010-03-20? Yep, the same as in the one of today.
Happy to serve with more info if required (and available..).
