Ok, I just started a tcpdump of connections going to my local machine. Suddenly, I got scrolling oopses, usually a bad sign.
Setup is 486dx50 (not dx2, dx) 4 meg/scsi/SMC ultra network card. Kernel is mostly bare + module ability + kerneld (but not running)
So looks like something stomped on the process table real hard. Just before this, something tried to kfree non kmalloced mermory, on the order of 119 meg. (this is a 4 meg machine)
kfree of non-kmalloced memory: 000583d0, next= 07790774, order=119539497
Unable to handle kernel paging request at virtual address c7200728 current->tss.cr3 = 00360000, *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[<0011ebf8>] swap_out_process + 0x58 EFLAGS: 00010202 eax: 07200720 ebx: 00232018 ecx: 00058158 edx: 00000000 esi: 00232018 edi: 00000001 ebp: ffffffff esp: 002f7ee0 ds: 0018 es: 0018 fs: 002b gs: 002b ss: 0018 Process testproc (pid: 17966, process nr: 16, stackpage=002f7000) Stack: 00232018 00000000 00000001 ffffffff 0011ed90 00232018 ffffffff 00000001 00000005 ffffffff 00000001 00000293 0011ee48 00000005 ffffffff 00000001 00000003 00000010 002f7fbc 0011f633 00000003 ffffffff 00000001 0041b958 Call Trace: [<0011ed90>] [<0011ee48>] [<0011f633>] [<00119456>] [<0010ff0e>] [<0010fda0>] [<0010a7ab>] Code: 39 50 08 76 13 39 50 04 76 de 89 c1 8b 40 14 eb eb 90 90 90 0011ed80: swap_out 0011ee48: try_to_free_page 0011f633: kswapd 00119456: clear_page_tables 0010ff0e: do_page_fault 0010fda0: si_meminfo 0010a7ab: error_code
Looks ugly... Like the error wanted memory causing a page-fault but the handler got stepped on.
All the others are the same.
Ideas?
