Wysocki" Cc: Linux Kernel Mailing List , Kernel Testers List , Maciej Rutecki , Florian Mickler I can confirm that this "regression" still exists with the kernel 2.6.37-rc8. The Call Trace is basically the same: ... Kernel panic - not syncing: map_single ... Pid 935, comm: NetworkManager Tainted call trace panic+oxbf/0x200 ? default_spin_lock_flags+0x9/0x10 ?swiotlb_tlb_map_single+0x1ce/0x250 ?map_single+0x46/0x60 swiotlb_map_page+0xa6/0xf ... and then the FREEZE ... only a hard reset brings to live (with 2.6.36-2) Linux. carlos.
