Hello kernel maintainers,
1st, please Cc me in reply.
I encounter the following kernel error using stock kernel.org 2.4.17:

<7>PPP: VJ decompression error
When this error occur, it happens very quickly on many more processes
(a totoal of 20 process, both kernel & user), killing them all, with
the same "kernel BUG" prefix. Of course, the machine ends-up in a
very bad state & I have to use the magic SysRq to sync it & reboot it.
Looking on various linux-kernel ML archives, I found that the VM is
having some troubles, but no failure with the same backtrace as the
one I have, whereas I always have exactly the same one, at least on
the 2 lowest levels:
[shrink_caches+78/128]
[try_to_free_pages+48/76]
differences from here:
[balance_classzone+102/576]
[__alloc_pages+258/348]
[read_swap_cache_async+92/152]
[swapin_readahead+55/68]
[do_swap_page+43/220]
[handle_mm_fault+107/192]
[set_termios+368/380]
[do_page_fault+363/1140]
[tty_check_change+63/120]
My box is a K6 200 with 64Mb cache, ~800Mb swap. It is my mail,news &
web proxy. It also does IP masquerading.
Anything else I can provide to you?
