Hello,
I first noticed this last night, after recompiling the kernel to fix
the delayed ACKs bug. What happens is that if I only use the network
"regularly" (fetchmail/web browsing/IRC/IM/etc), the system seemed to
run normally. But after launching a gnutella client, the system panics
with the following message on the console (the first 3 times it
occurred I was running gtk-gnutella, so I thought it could be either
gtk-gnutella- or X-related and tried with mutella on the console with
the same result):
Fatal trap 12: page fault while in kernel mode
fault virtual address =3D 0x2e405
fault code =3D supervisor write, page not present
instruction pointer =3D 0x8:0xc025d976
stack pointer =3D 0x10:0xcce85cd8
frame pointer =3D 0x10:0xcce85ce0
code segment =3D base 0x0, limit 0xfffff, type 0x1b
=3D DPL 0, pres 1, def32 1, gran 1
processor eflags =3D interrupt enabled, resume, IOPL =3D 0
current process =3D 13 (swi6: tty:sio clock)
trap number =3D 12
panic: page fault
syncing disks, buffers remaining... panic: bwrite: buffer is not busy???
Uptime: 32m54s
pfs_vncache_unload(): 2 entries remaining
Automatic reboot in 15 seconds - press a key on console to abort
I remember I reported a trap about 2 years ago for a 4.x-STABLE
system, and when I pasted the error message someone asked me to
perform other steps to further investigate what was going on. But I
can't seem to remember what those steps were, so if anyone needs any
other info, just ask and I'll provide.
Fred
