Hi, I've been playing with the KDB kernel debugger, and trying to figure out why it doesn't enter into the debugger during a kernel panic. I tracked the problem to the IPMI panic handler.
When I have the Sytem Interface option enabled in the kernel (or the ipmi_si module loaded), I don't get to KDB and the system just hangs in the first i_ipmi_request() in the send_panic_events() function. Without the SI loaded, the rest of the panic handlers run and eventually the KDB panic handler is invoked. I'm not sure if this is device-specific, but here are the ipmi-related dmesg: [ 5.356557] ipmi message handler version 39.2 [ 5.369593] ipmi device interface [ 5.379627] IPMI System Interface driver. [ 5.391644] ipmi_si: Trying SMBIOS-specified kcs state machine at i/o address 0xca2, slave address 0x20, irq 0 [ 5.503192] ipmi: Found new BMC (man_id: 0x000157, prod_id: 0x0028, dev_id: 0x20) [ 5.525939] IPMI kcs interface initialized I've reproduced this on the SuSE sles11 kernel as well as upstream kernels (2.6.28 and up to 2.6.31-rc2). Any ideas? mh ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
