Something with the latest e1000 update in current causes a panic during
attach on my laptop. Rolling sys/dev/e1000 back to the previous version
fixes the problem. Here's the hand transcribed panic:
panic: mtx_lock() of spin mutex &dev_spec->swflag_mutex @ ../../../dev/e1000/e1000_ich8lan.c:651
The back trace places me at: e1000_acquire_swflag_ich8lan()+0x30
The device in question is in my lenovo x61s laptop and the pciconf
output is:
em0@pci0:0:25:0: class=0x020000 card=0x20de17aa chip=0x10498086 rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = 'Gigabit Network Connection Interface Controller (82566MM NIC)'
class = network
subclass = ethernet
Thanks,
Brooks
