Summary: crash on eth trafic on machines without parallel port Project: The GNU Hurd Submitted by: sthibaul Submitted on: mer 03 mar 2010 02:42:03 CET Category: GNU Mach Severity: 3 - Normal Priority: 5 - Normal Item Group: None Status: None Privacy: Public Assigned to: None Originator Name: Originator Email: Open/Closed: Open Discussion Lock: Any Reproducibility: None Size (loc): None Planned Release: None Effort: 0.00 Wiki-like text discussion box: _______________________________________________________ Details: On machines without a parallel port (e.g. qemu -nodefaults without a -parallel option), network trafic or simply devprobe eth0 gives general protection faults like: Kernel Genreal protection trap, eip 0x1031ba kernel trap, type 13, code 25a EAX 00000006 EBX 20000d38 ECX 0000001c EDX 00000006 ESI 002d2b20 EDI 002d2c34 EBP 253a1fb0 ESP 0012bc37 CS 0008 SS 1e41 DS 0010 ES 0010 FS 0010 GS 0010 v86: DS 002c ES 0000 FS 31ba GS 31ba EIP 001031ba EFLAGS 00000293 trapno 13: General protection , error 0000025a panic: trap here, this is at the ret of the end of the spl() function. I guess there's a problem with irq handling when irq 7 is not used by the parallel port driver, leading to something like a stack overflow or such. Note in the figures above that EBP and ESP are very different, and 0x0012bc37 is in the middle of GNU Mach itself! _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?29048> _______________________________________________ Message posté via/par Savannah http://savannah.gnu.org/
