BUG: spinlock bad magic on CPU#0, kswapd0/242 (Not tainted) lock: c06c9380, .magic: c06c9380, .owner: [] _raw_spin_lock+0x1a/0xd9 [] _spin_lock_irqsave+0x9/0xd [] __wake_up+0x18/0x43 [] __wake_up_bit+0x2e/0x33 [] shrink_inactive_list+0x483/0x6c9 [] shrink_active_list+0x334/0x33c [] shrink_zone+0xbd/0xe2 [] kswapd+0x296/0x3bb [] autoremove_wake_function+0x0/0x35 [] kswapd+0x0/0x3bb [] kthread+0xb0/0xd9 [] kthread+0x0/0xd9 [] 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 (normally posting from blob@blob.co.uk but can't get to that as the server is crashed!)
