| |
Hi,
I just wondered if the below type of crash was a known thing, and if there are any obvious things I can do to prevent/fix it ?
BUG: spinlock bad magic on CPU#0, kswapd0/242 (Not tainted) lock: c06c9380, .magic: c06c9380, .owner: [<c06eba2a>] _raw_spin_lock+0x1a/0xd9 [<c061e72f>] _spin_lock_irqsave+0x9/0xd [<c041febf>] __wake_up+0x18/0x43 [<c04379ce>] __wake_up_bit+0x2e/0x33 [<c045a496>] shrink_inactive_list+0x483/0x6c9 [<c0459eae>] shrink_active_list+0x334/0x33c [<c045a799>] shrink_zone+0xbd/0xe2 [<c045ac0e>] kswapd+0x296/0x3bb [<c04379e9>] autoremove_wake_function+0x0/0x35 [<c045a978>] kswapd+0x0/0x3bb [<c043792f>] kthread+0xb0/0xd9 [<c043787f>] kthread+0x0/0xd9 [<c0404b47>] kernel_thread_helper+0x7/0x10 =======================
The .owner: field contains a long list of unprintable characters.
The server is running kernel-smp-2.6.20-1.2307.fc5.i686.rpm. Hardware of note is:
1x AMD AM2 DUALCORE 3800 2x Corsair DDR2 XMS 1Gb PC6400 2x 400G SEAGATE SATA2 ST3400633AS (traditional s/w RAID1 w/ ext3) 1x ASUS M2V-MX AM2 MOBO (onboard NIC unused) 1x e100 driver using NIC
I've a few things to try (disabling serial/par ports, unused NIC, USB). It also crashed with a UP kernel.
Apologies if I'm duplicating any questions asked, I Googled for the error messages but found quite different stack traces and contextx (e.g. resiferfs vs ext3 - i'm only running ext3)
Regards, Ian
