SubjectBuffer-Werner-17-jul: Deadlock again..
Yeap, my machine just frozen while compiling pre-2.1.46-1. I'm using
2.0.30 + pre31-2, with Werner's buffer patch of july 17 _without_ removing

> /* Give the physical reallocated page a bigger start */
> mem_map[MAP_NR(page)].age = (2*PAGE_INITIAL_AGE);

this. Total uptime with this kernel (or any kernel with this buffer patch)
was 5 hours approx.

Complete list of patch in this kernel:

1 ./ 0 ext2-error 0 pre31-2
1 ../ 0 filehandle 0 stack-exec
0 buff-werner-17-jul 0 ft

I also got this message in the logs from this kernel, way before the crash,
while dumping a large file from a scsi dat tape with
'dd if=/dev/nst0 of=file bs=32k'

Jul 19 15:10:19 lili kernel: try_to_free_page: free pages 932kB, async pages
0kB

When the crash occured, i was on a the VC doing the compile, with X running
and eating its normal (huge) memory requirement.

My hardware setup is P5 166, 430FX, 64MB RAM, ncr53c810 scsi adapter and ncrBsd
driver.
NOTE: my RAM setup is the following: 2 matched simms bought one year ago (2x16M)
and 2 more matched simms bought last week. I know (by personal experience with
low quality and unmatched pair of simms) that this kind of setup _may_ lead to
problem. Anyway, I run this setup since 7 days, with a lot of compilation,
without a problem. But without ECC, I can't be sure that it's not hardware
related. Seeing Miquel's news server crashing in the same (silent) way, I think
this is more likely software related.

Software setup is development debian of yesterday (debian hamm)

Cheers.
