           Summary: bnx2_poll_work kernel panic
           Product: Drivers
           Version: 2.5
     KernelVersion: 2.6.27.15
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Network
        AssignedTo: jgarzik@pobox.com
        ReportedBy: pmjdebruijn@pcode.nl


Latest working kernel version: 
  2.6.22.19

Earliest failing kernel version: 
  2.6.27.15 
  We did not test kernel versions in between 2.6.27.15 and 2.6.22.19

Is a regression.

Distribution: 
  Debian GNU/Linux 4.0r6 (fully updated), with self built vanilla kernel.

Hardware Environment: 
  HP DL360 G5, with two onboard Broadcom Corporation NetXtreme II BCM5708
Gigabit Ethernet Controllers

Software Environment:
  Debian GNU/Linux 4.0r6 using rsync 3.0.3

Problem Description:
  After initializing daily (nightly) rsync backups our backup server panics
with the following call trace (we've had this issue twice, so we downgraded our
kernel).

The following call trace was captured using a digital camera and reproduced as
the following text:

[24756.632218] Kernel panic - not syncing: Fatal exception in interrupt

Steps to reproduce:
1. Boot server using 2.6.27.15 kernel
2. Start several (about 10) simultaneous rsync processes to the server
3. Wait for crash

There's a partial screenshot in bugzilla.  It crashed in
bnx2_poll_work().
