Hi. I'm not subscribed, so please cc me on any replies. I'm getting an oops when trying to mount a FAT32 partition hosted on another machine on my home network. The kernel is built from a pull of from kernel.org this morning. "git describe" gives v3.3-rc2-37-gbd3ce7d. The oops message is: CIFS VFS: default security mechanism requested. The default security mechanism will be upgraded from ntlm to ntlmv2in kernel release 3.3 BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<c116b146>] strnlen+0x6/0x20 *pdpt = 0000000033f0c001 *pde = 0000000000000000 Oops: 0000 [#1] PREEMPT SMP Modules linked in: md4 cifs ipt_LOG xt_state iptable_filter ipt_MASQUERADE iptable_nat nf_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_conntrack psmouse r8169 [last unloaded: microcode] Pid: 811, comm: mount.cifs Not tainted 3.3.0-rc2+ #94 Hewlett-Packard HP G61 Notebook PC/3069 EIP: 0060:[<c116b146>] EFLAGS: 00010207 CPU: 0 EIP is at strnlen+0x6/0x20 EAX: 00000000 EBX: f31149ac ECX: 00000000 EDX: 000000ff ESI: f32a1df4 EDI: f31149b0 EBP: f1a63830 ESP: f32a1d88 DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Process mount.cifs (pid: 811, ti=f32a0000 task=f1a78380 task.ti=f32a0000) Stack: f943a9aa f3114900 9a734c2c 00000000 f1a63800 f943b64a f32a1df0 00000001 c1047be2 00000000 00000001 00000000 00000001 c1087bf1 f1bfc380 c14d9a80 00000000 00000007 00000001 f3da7a40 f45dc1c0 00000041 00000000 00000000 Call Trace: [<f943a9aa>] ? ascii_ssetup_strings.isra.7+0x3a/0xd0 [cifs] [<f943b64a>] ?
