When exercising the built-in "UniNEnet" gigE interface on a powerbook, I noticed
that OS-X 10.2.4 falls over rather quicky under load.
Trying 'netperf -tUDP_STREAM -Hsome-fast-host -- -m 1472', I saw:
panic(cpu 0): 0x300 - Data access
Latest stack backtrace for cpu 0:
Backtrace:
0x00084FAC 0x000853DC 0x00027FA8 0x0008EE68 0x00091F78
Proceeding back via exception chain:
Exception state (sv=0x19269000)
PC=0x001F82EC; MSR=0x00009030; DAR=0x00000008; DSISR=0x40000000;
LR=0x001007D8; R1=0x11DF3B70; XCP=0x0000000C (0x300 - Data access)
Backtrace:
0x00000000 0x001007D8 0x0010B9CC 0x001FB4DC 0x001FF788
0x001FF8C0 0x0020E59C 0x00092110
0x00430053
Exception state (sv=0x1969F280)
PC=0x9001352C; MSR=0x0000D030; DAR=0x17170000; DSISR=0x42000000;
LR=0x0000856C; R1=0xBFFFF600; XCP=0x00
000030 (0xC00 - System call)
This looks like:
001f8258 A _m_copym
000ff964 A _ip_output
0010b810 a _udp_output
001fae04 A _sosend
001ff544 a _sendit
001ff864 A _sendto
0020e34c A _unix_syscall
Interestingly, I can get this to happen on an 867MHz powerbook, but
not on a dual 800MHz G4.
Just thought y'all might be interested.
Cheers,
Drew
