2.6.1-rc2 + aha152x still oopses
From: Oliver Feiler
Date: Wed Jan 28 2004 - 09:01:09 EST
Hi,
this is related to my post from Jan 7th, see
http://lkml.org/lkml/2004/1/6/202.
The Oops in the aha152x driver was supposed to be fixed in 2.6.1-rc1 from what
I was told. I've been running 2.6.1-rc2 and indeed it didn't happen with that
kernel. Today however I got a slightly different oops with the same kernel. I
didn't see any changes to the driver since 2.6.1-rc2 so I didn't upgrade
(takes a long time to compile on a 486).
I got two oopses which I attached to this mail. After that the system needed
to be resetted. Is this a new problem or did I just miss changes to the
driver and it is already fixed in 2.6.2-rc2?
Bye,
Oliver

ksymoops 2.4.8 on i486 2.6.1-rc2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.6.1-rc2/ (default)
-m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
