Subject: crash of latest trunk on SMP
Date: Tue, 30 Jan 2007 09:48:23 +0100 [thread overview]
Message-ID: <20070130084823.GA15490@elte.hu> (raw)
FYI, UP works fine, but a 32-bit SMP host crashes with latest trunk:
BUG: at arch/i386/kernel/smp.c:177 send_IPI_mask_bitmask()
[<c0104d6b>] show_trace_log_lvl+0x19/0x2e

[<c01712ce>] sys_ioctl+0x48/0x62

=======================
i suspect vcpu->cpu might be something uninitialized, like -1?
