E-mail: jt@hpl.hp.com From: Jean Tourrilhes Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, Maybe it would be a good idea to fix or revert the hp100 patch that went into 2.6.3 : ---------------------------------------------------------- # modprobe hp100 FATAL: Error inserting hp100 (/lib/modules/2.6.3/kernel/drivers/net/hp100.ko): No such device # dmesg [...] hp100: Busmaster mode enabled. hp100: at 0xf400, IRQ 16, PCI bus, 32k SRAM (rx/tx 75%). hp100: Adapter is attached to 100Mb/s Voice Grade AnyLAN network. # cat /proc/net/dev Segmentation fault # dmesg [...] hp100: Busmaster mode enabled. hp100: at 0xf400, IRQ 16, PCI bus, 32k SRAM (rx/tx 75%). hp100: Adapter is attached to 100Mb/s Voice Grade AnyLAN network.

This is with a PCI card. Looking at the changes, they would also require testing with a ISA card (which I don't have in my box at the moment). 2.6.2 works perfectly. This is what 2.6.2 looks like : --------------------------------------------- hp100: eth1: Busmaster mode enabled. hp100: eth1: HP J2585B at 0xf400, IRQ 16, PCI bus, 32k SRAM (rx/tx 75%). hp100: eth1: Adapter is attached to 100Mb/s Voice Grade AnyLAN network. --------------------------------------------- Also : ----------------------------------- 00:12.0 Ethernet controller: Hewlett-Packard Company J2585B Subsystem: Hewlett-Packard Company J2585B DeskDirect 10/100VG NIC Flags: bus master, medium devsel, latency 64, IRQ 16 I/O ports at f400 [size=256] Memory at fedfc000 (32-bit, non-prefetchable) [disabled] [size=8K] ----------------------------------- Have fun...
