Subject: "kernel BUG at page_alloc.c:102!" (kernel 2.4.20)
Date: Mon, 17 Mar 2003 06:46:20 -0500 [thread overview]
Message-ID: <8EE4126620031047901034.13328.smtp@valaran.com> (raw)
Greetings.
On a relatively idle system (used mainly for syslog things) that had
been up for ~42 days, kswapd croaked and the kernel claimed (sorry if
these lines are wrapped):
kernel BUG at page_alloc.c:102!

The box is essentially a LinuxFromScratch (actually a severely
overhauled SuSE 6.2) box. Vanilla kernel 2.4.20 (no patches), glibc
2.2.5, gcc 2.95.3. It's all running on an Abit KT7A mainboard (Athlon
1.4GHz) with 640MB or so of RAM.
I rebooted the box but it hung when trying to turn off swap. :-) (BTW,
is there a means by which to "restart" kswapd if need be?)
I've been using 2.4.20 since a few days after its release. This is the
first time I've seen this "kernel BUG"; I have absolutely no idea what
triggered it, nor how to reproduce it.
If you need more info, just ask!
Regards,
krjw.
