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.
