Interesting. Sounds like initialization issues.

FYI, it must be something old, the behavior is the same i reported here http://lkml.org/lkml/2008/4/21/454 with 2.6.24. > at 32bit and CONFIG_DEBUG_SPINLOCK unset (both gcc 4.3 & 4.4) i get > the build error i reported in another thread. with CONFIG_DEBUG_SPINLOCK > set kernel builds and runs nicely. -----[ Domenico Andreoli, aka cavok --[ http://www.dandreoli.com/gpgkey.asc ---[ 3A0F 2F80 F79C 678A 8936 4FEE 0677 9033 A20E BC50 -- To unsubscribe from this list: send the line "unsubscribe linux-parisc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
