[Bug 1712746] Re: mwifiex causes kernel oops when AP mode is enabled
This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed- xenial'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Bug 1712746] Re: mwifiex causes kernel oops when AP mode is enabled
** Description changed: When it's in AP mode, there's quite a chance to find kernel oops during reboot. + This is caused by the wiphy may be NULL for some reason. It's likely a + bug in mwifiex. We've already pinged Marvell and Murata. Before there's + a real fix available, we should check wiphy before accessing it. + + I've tried a 4.13-rc6 kernel. Though it has oops for NULL pointer + deference too, it happens in a different function in mwifiex. Thus the + workaround for Xenial may or may not help for other series. Will need to + reproduce this issue with Zesty and then we can decide whether this + workaround should be applied to Zesty. + [ 30.701441] BUG: unable to handle kernel NULL pointer dereference at 00f0 [ 30.709511] IP: [] mwifiex_get_cfp+0x49/0x150 [mwifiex] - [ 30.716494] PGD 0 - [ 30.718575] Oops: [#1] SMP + [ 30.716494] PGD 0 + [ 30.718575] Oops: [#1] SMP [ 30.721918] Modules linked in: ipt_MASQUERADE nf_nat_masquerade_ipv4 iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_nat nf_conni [ 30.836915] CPU: 1 PID: 679 Comm: kworker/u5:0 Not tainted 4.4.0-57-generic #78-Ubuntu [ 30.845018] Hardware name: Dell Inc.
