Bug#490903: regression: kernel panic on boot with megaraid_mbox driver

[Daniel Dickinson <cshore@fionavar.ca>]

Package: linux-image-2.6.25-2-686
Version: 2.6.25-6
Severity: important


I just attempted to upgrade to 2.6.25-2-686 and discovered that if .25 were released as is, I'd be unable to use debian on this system.  The kernel panics during boot.  It happens after entering cryptsetup password and occurs in the megaraid_mbox driver.  Based on when it happens and the driver it happens to I am guessing it is a result of the st tape driver (the part that (used to?) gives the block count and such.  (The inital st driver load seems to be okay, although the messages scroll by too quickly for me to be sure, but if it loads at the same time as before the load of st driver succeeds, but when it tries to attach to a specific drive it panics.

This is a Dell PERC3/DC RAID controller which is basically an AMI MegaRAID Elite 1600.  I, however, have one channel for the RAID, and a second channel for a scanner and tape drive (non-RAID).  It works fine with 2.6.24-1-686 which I am back to using for now.
