I was having VM oopsen with 2.4.19rc1aa1, so I upgraded to 2.4.19rc2aa1
to see if things were any better. Apparently they aren't.
System uptime of about 60 hours. P3-1G, 512M RAM. Pretty standard
system. This time it wasn't postgresql that got whacked, it was scp.
I'm probably going to fall back to 2.4.19rc3 soon. This is a production
machine, so I can't reboot it that often... The -aa kernel does
bring a number of benefits (and I'm hoping to not have to pull the bits
I want out; I hate rediffing things..)
Here's the ksymoops dump. NULL dereference in the middle of
page_cache_read.
ksymoops 2.4.4 on i686 2.4.19-rc2aa1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.19-rc2aa1/ (default)
-m /boot/System.map-2.4.19-rc2aa1 (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.
