I'm seeing many of these on dmesg, almost everytime a module is getting loaded:
BUG: sleeping function called from invalid context insmod(1357) at kernel/rt.c:1322 in_atomic():1 [00000001], irqs_disabled():1 [<c0105040>] dump_stack+0x23/0x25 (20) [<c0116026>] __might_sleep+0xbc/0xcf (36) [<c01321d1>] __spin_lock+0x38/0x57 (24) [<c013220d>] _spin_lock+0x1d/0x1f (16) [<c0145386>] kmem_cache_alloc+0x3f/0xfe (32) [<c01358ff>] use_module+0xa8/0x13a (32) [<c01363db>] resolve_symbol+0x79/0x8c (40) [<c0136a1d>] simplify_symbols+0xc4/0xfe (44) [<c013779b>] load_module+0x64f/0x989 (144) [<c0137b2c>] sys_init_module+0x57/0x23d (32) [<c0104201>] sysenter_past_esp+0x52/0x71 (-8124) --------------------------- | preempt count: 00000002 ] | 2-level deep critical section nesting: ---------------------------------------- ..

Another critical issue is that USB is not working properly; the ohci_hcd module gets loaded but devices don't get listed by lsusb at all, which I think is a "bonus" from upstream 2.6.9-rc1-mm3.
In fact I think -mm3 is breaking many things around here, at least on my laptop; another notorious is my wifi stuff (linux-wlan-ng/prism2_cs) now failing due to unresolved symbols, such as these:
prism2_cs: Unknown symbol p80211netdev_rx prism2_cs: Unknown symbol register_wlandev prism2_cs: Unknown symbol wlan_unsetup prism2_cs: Unknown symbol unregister_wlandev prism2_cs: Unknown symbol p80211netdev_hwremoved prism2_cs: Unknown symbol wlan_setup prism2_cs: Unknown symbol p80211skb_rxmeta_attach
But I guess this is off-topic by now.
