SMP Frequent Lockups
Sat Aug 2 05:55:21 PDT 2003
I've had the same with my Netgear PCI card with kernel 2.4.20 (I tried
the provided kernel RPMs (rebuilt for SMP of course) and tried with the
latest (030722) hostap from cvs patched in to the same kernel.
The machine works fine (no lockups in weeks of use) with a UP kernel,
but in SMP it will hard lock requiring a powercycle within a few
localhost kernel: hostap_pci: Registered netdevice wlan0
localhost kernel: prism2_hw_init()
localhost kernel: prism2_hw_init: initialized in 17954 iterations
localhost kernel: wlan0: NIC: id=0x8013 v1.0.0
localhost kernel: wlan0: PRI: id=0x15 v1.0.7
localhost kernel: wlan0: STA: id=0x1f v1.3.6
localhost kernel: wlan0: defaulting to host-based encryption as a workaround for firmware bug in Host AP mode WEP
localhost kernel: wlan0: defaulting to bogus WDS frame as a workaround for firmware bug in Host AP mode WDS
localhost kernel: wlan0: Intersil Prism2.5 PCI: mem=0xe4000000, irq=16
localhost kernel: hostap_crypt: registered algorithm 'WEP'
I've now moved to a uniprocessor machine, but if you need me to I could
swap cards back and do some tests (if nobody else can).
Thanks for the great work so far.

Previously ive had only 1 or 2 lockups (non SMP kernel) using Hostap 0.0.3 under heavy traffic (FTP for instance) over a 3 month span. Now with the SMP kernel I have lockups with even light usage of the wireless AP (ssh or webbrowsing). These are hard lockups that require cycling the power via unplugging. I can verify that the lockups only happen with some sort of traffic on the wireless card, as I can keep the hostap module loaded with the interface down, and not crash. Anyone have a solution?
