Hello,
I just compiled kernel 2.5.26 but I can't get it to boot up as it always
panics when it gets to the scsi devices.
I have a Adaptec 2939U SCSI controller and a Sony SDT-9000 DDS-3 tape
drive connected to it.
The aic7xxx is built-in to the kernel along with the tape support as well as
scsi cdrom support and the scsi-emulation driver for my CD-RW.
Here's the panic output:
Unable to handle NULL pointer dereference at virtual address 0000000c
printing eip:

*pde = 00000000

In interrupt handeler - not syncing
I didn't run a ksymoops on it since I cannot boot 2.5.26 so I can't use its
/proc/modules and /proc/ksym. Okay well I did a ksymoops against my current
kernel 2.4.18 but using 2.5.26 sys map and its modules. I'm not sure if this
has any value since it was made using a wrong version but here's it output:

I don't have much experience submiting kernel bugs as you have probably
noticed from this post, but if you need anything else to trace this thing now
let me know and I'll provide it.
As a side note I just tested 2.5.25 and it gives the same error.
Cheers,
Alex.

Alexandru,
This error has a signature similiar to what Patrick Mansfield
reported previously. You can review the previous thread here.
http://marc.theaimsgroup.com/?t=101494907100009&r=1&w=2
In the thread a temp workaround was mentioned but not a perm
solution.
