The unwinder-based backtrace is screwed up (yet again) but the old-style
backtrace is there, in all its messy glory.
Weeding out the crap, I think it's this:
[<c01d03af>] delay_tsc+0xb/0x13
[<c01d03e0>] __delay+0x6/0x7
[<c022c240>] _tw32_flush+0x3f/0x51
[<c022da97>] tg3_switch_clocks+0x8f/0x93
<I assume tg3_init_hw() got inlined>
[<c0237673>] tg3_open+0x250/0x520
[<c02d3263>] dev_open+0x2b/0x62
[<c02d1dd8>] dev_change_flags+0x47/0xe4
[<c0307fcc>] devinet_ioctl+0x252/0x556
[<c02d2e5a>] dev_ifsioc+0x113/0x38d
[<c02d29c4>] dev_load+0x24/0x4b
[<c02c9265>] sock_ioctl+0x19e/0x1c2
It's strange that the post-2.6.19-rc2 changes triggered this - that code
won't have run yet.
Norbert, are you really sure?
