This bug is strange. I do not see NULL pointer dereference, %rdi is ffff8800797b9990, and dissembled corresponding code looks like below: objdump -d -r --prefix-addresses /lib/modules/3.9.9-201.fc18.x86_64/kernel/net/wireless/cfg80211.ko | grep -A 3 -B 3 "<cfg80211_chandef_valid+0xc>" > 0000000000024ce5 <cfg80211_chandef_valid+0x5> mov (%rdi),%rax > 0000000000024ce8 <cfg80211_chandef_valid+0x8> push %rbp > 0000000000024ce9 <cfg80211_chandef_valid+0x9> mov %rsp,%rbp > 0000000000024cec <cfg80211_chandef_valid+0xc> test %rax,%rax <- RIP HERE > 0000000000024cef <cfg80211_chandef_valid+0xf> je 0000000000024de8 <cfg80211_chandef_valid+0x108> > 0000000000024cf5 <cfg80211_chandef_valid+0x15> movzwl 0x4(%rax),%edx > 0000000000024cf9 <cfg80211_chandef_valid+0x19> xor %eax,%eax So this looks like CPU state corruption or some memory corruption. I looked at some other bugs you reported (bug 986226 and bug 987780), both have some pointer corrupted i.e. ff0088007b454960 instead of ffff88007b454960, so that's real problem on your system. Please run memtest to see if your memory works correctly, if memtest will not find any problems, please install kernel-debug and run on that kernel , it could detect issues, i.e. driver that corrupt memory. *** Bug 986226 has been marked as a duplicate of this bug. *** *** Bug 987780 has been marked as a duplicate of this bug. *** The needinfo request[s] on this closed bug have been removed as they have been unresolved for 1000 days |
