Subjectkernel BUG at drivers/serial/core.c:1067 with 2.5.44
From
Date
i get the following on a pentium iii 650 MHz sony vaio at boot time:

ksymoops 2.4.6 on i686 2.5.44. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.5.44/ (default)
-m /boot/System.map-2.5.44 (default)
-x

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.

1 warning issued. Results may not be reliable.

the funny thing is i've been running this kernel since it came out and
the oops didn't happen until today. i disabled irda in the bios and
now i can boot again. i am attaching my .config file.
