Description b2566996 2011-06-02 14:56:20 UTC
* Any Windows machine writes to a Samba share on a Fedora machine it will crash the Fedora operating system every time.
* The Windows machine can consistently read with no trouble.
* An Ubuntu machine can read and write to the same share and as the same user without incident.
* It was working fine for nearly a year and stopped recently without modification to the system or config files except for updates.
* Nothing gets logged in /var/log/messages.  It just cuts off until hardboot.
*  The only thing logged in /var/log/samba/* is many instances of this: "[2011/05/29 17:01:52.267773,  0] smbd/nttrans.c:2271(call_nt_transact_ioctl)   call_nt_transact_ioctl(0x900eb): Currently not implemented" but it does not correlate with the times the machine crashes.
* The problem persists when writing to /dev/shm via samba to rule out hard disk.
* Uninstalled and reinstalled Samba.
* Memtest checked out OK.
* Disabled IPv6 on Windows.
* Samba version: 3.5.8-76.fc14.
* Tried kernels: 2.6.35.11-83.fc14.i686  2.6.35.13-91.fc14.i686 and 2.6.35.12-90.fc14.i686

Weird. If it really crashes the box hard, I'd say this is not a Samba bug.

Günther, have you seen this before in Fedora?

It turned out to be a bad NIC. Added in a second NIC, gave it the original IP, and told samba to look at the new interface... So far everything seems to be working. :/ Thanks for checking into it.

Please re-open if it turns out to be more Samba-specific
