Well, I've got some data from earlyprintk (forgot I needed to boot with vga=normal). Unfortunately, I had to rewrite the trace manually: clear_IO_APIC_pin+0x15/0x6a try_apic_pin+0x7a/0x98 setup_IO_APIC+0x600/0xb7a smp_prepare_cpus+0x33a/0x371 init+0x60/0x32d child_rip+0xa/0x12 [And then the unwinder said it got stuck.] RIP is reported to be at ioapic_read_entry+0x33/0x61, which according to gdb is: 0xffffffff80271418 is in ioapic_read_entry (include/asm/io.h:204). 199 200 #define mmiowb() 201 202 static inline void __writel(__u32 b, volatile void __iomem *addr) 203 { 204 *(__force volatile __u32 *)addr = b; 205 } 206 static inline void __writeq(__u64 b, volatile void __iomem *addr) 207 { 208 *(__force volatile __u64 *)addr = b; > > I'm unable to reproduce the problem on a non-SMP box (Asus L5D), which works > > just fine with this kernel, Well, it's booted with 'noapic', so no wonder ... > > but on the other SMP box the framebuffer is broken > > (displays all fonts inverted, as in a mirror) > > Which fbdev driver?

Tomorrow I'll try a serial one, but now I must get some sleep (I can hardly see anything). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
