Revision 84ffae55af79d7b8834fd0c08d0d1ebf2c77f91e authored by Anton Blanchard on 07 April 2011, 21:44:21 UTC, committed by Benjamin Herrenschmidt on 18 April 2011, 03:08:19 UTC
We currently enable interrupts before the dispatch log for the boot cpu is setup. If a timer interrupt comes in early enough we oops in scan_dispatch_log: Unable to handle kernel paging request for data at address 0x00000010 ... .scan_dispatch_log+0xb0/0x170 .account_system_vtime+0xa0/0x220 .irq_enter+0x88/0xc0 .do_IRQ+0x48/0x230 The patch below adds a check to scan_dispatch_log to ensure the dispatch log has been allocated.
