Can somebody please help me with the following:
I'm connecting to the Internet using a (Cisco) Linksys WUSB54GC wireless USB
adapter with FreeBSD 7.0-RELEASE and its rum driver.
The device gets recognized, wpa_supplicant can associate to the WLAN, DHCP
obtains an IP address, all works fine. I can browse the Web with Lynx no
problems. But when I try to download a larger file (e.g. fetch a port or
package...), sooner or later (and usually sooner rather than later) a page
fault occurs and the kernel panics.
I've examined several crash dumps and they all mention the same instruction
pointer (for the standard GENERIC kernel that comes with 7.0-RELEASE):
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x12
fault code = supervisor read, page not present
instruction pointer = 0x20:0xc06b9e7a
stack pointer = 0x28:0xe58f2be4
frame pointer = 0x28:0xe58f2bfc
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 23 (irq23: uhci0 ehci0)
trap number = 12
panic: page fault
cpuid = 0
Uptime: 1m9s
Physical memory: 2033 MB
Dumping 179 MB: 164 148 132 116 (CTRL-C to abort) 100 84 68 52 36 20 4
#0 doadump () at pcpu.h:195
195 pcpu.h: No such file or directory.
in pcpu.h
This can be traced back to somewhere within the rum driver:
(kgdb) list *0xc06b9e7a
0xc06b9e7a is in rum_txeof (/usr/src/sys/dev/usb/if_rum.c:842).
837 {
838 struct rum_tx_data *data = priv;
839 struct rum_softc *sc = data->sc;
840 struct ifnet *ifp = sc->sc_ic.ic_ifp;
841
842 if (data->m->m_flags & M_TXCB)
843 ieee80211_process_callback(data->ni, data->m,
844 status == USBD_NORMAL_COMPLETION ? 0 :
ETIMEDOUT
);
845
846 if (status != USBD_NORMAL_COMPLETION) {
(kgdb)
Thanks in advance for any help,
Alphons

All right, that does it Bill [Donahue]. I'm pretty sure that killing Jesus
is not very Christian.
