The NIC (Network interface card) on my HP9000 735/99 doesn't work with hppa-sources-2.6.10-pa11, no matter whether the lasi_82596 driver is compiled statically in the kernel or as a module. The driver wants to use IRQ 17, which is already used by "HP SDC NMI", according to /proc/interrupts. The driver works flawless with hppa-sources-2.4.26-pa4 an hppa-sources-2.6.10-pa2. I believe that this is a problem with the new interrupt code introduced in hppa-sources-2.6.10-pa4 (This is an estimation). Reproducible: Always Steps to Reproduce: 1. emerge =hppa-sources-2.6.10-pa11 2. configure and compile the kernel 3. install it in palo 4. boot the machine with the new kernel Actual Results: the NIC didn't work, with the followin messages: Feb 2 19:14:07 hp LASI 82596 driver - Revision: 1.30 Feb 2 19:14:07 hp Found i82596 at 0xf0826000, IRQ 17 Feb 2 19:14:07 hp drivers/net/lasi_82596.c: MAC of HP700 LAN read from EEPROM Feb 2 19:14:07 hp eth0: 82596 at 0xf0826000, 08 00 09 49 85 F2 IRQ 17. Feb 2 19:14:14 hp eth0: IRQ 17 not free (built-in and module created similar messages) Expected Results: the NIC should have got a free interrupt and work normally Machine: HP9000 735/99 with 176 MB RAM and single-ended SCSI disks NIC: Standard BNC "Thin LAN" Daughterboard A2831A Graphics card: CRX EISA card: none

I 've tested multiple kernel versions and the results are the following: hppa-sources-2.6.10-p2: network works, interrupts are CPU00 2: 0 EISA cascade 32: 1496943 PARISC-CPU timer 35: 3355653 PARISC-CPU asp 85: 0 Cutoff EISA 86: 175881 Cutoff 2:0:1 87: 590 Cutoff i82596 88: 0 Cutoff parport0 90: 9 Cutoff serial 93: 0 Cutoff HP SDC NMI 94: 3181388 Cutoff HP SDC which are the same interrupts as in 2.4 kernels hppa-sources-2.6.10-p4 and hppa-sources-2.6.10-p6: network works an zhe interrupts are CPU00 2: 0 EISA cascade 32: 26214 CPU timer 35: 69616 CPU asp 64: 1 GSC-ASIC HP SDC NMI 65: 65037 GSC-ASIC HP SDC 69: 9 GSC-ASIC serial 71: 0 GSC-ASIC parport0 72: 39 GSC-ASIC i82596 73: 4576 GSC-ASIC 2:0:1 74: 0 GSC-ASIC EISA hppa-sources-2.6.10-p10 and hppa-sources-2.6.10-p11: network does not work and the interrupts are CPU0 2: 0 EISA cascade 16: 3114 GSC-ASIC 2:0:1 17: 0 GSC-ASIC HP SDC NMI 18: 75085 GSC-ASIC HP SDC 19: 9 GSC-ASIC serial 21: 0 GSC-ASIC parport0 25: 0 GSC-ASIC EISA 64: 34026 CPU timer 67: 78163 CPU asp all 2.6 kernels used the .config posted above, but with CONFIG_LASI_82596=y
I just installed linux-2.6.11-pa2 which I obtained directly from http://cvs.parisc-linux.org/download/linux-2.6/ as it is not yet in portage. The interrupt numbers again changed, IRQ17 was cleared for i82596, HP SDC NMI moves to IRQ19, serial to 20 ect. the content of /proc/interrupts is now CPU0 2: 0 EISA cascade 16: 3539 GSC-ASIC 53c700 17: 244 GSC-ASIC i82596 18: 466161 GSC-ASIC HP SDC 19: 0 GSC-ASIC HP SDC NMI 20: 8 GSC-ASIC serial 22: 0 GSC-ASIC parport0 24: 0 GSC-ASIC harmony 26: 0 GSC-ASIC EISA 64: 169573 CPU timer 67: 469923 CPU asp and the NIC works again. I made oldconfig from the .config posted above, but with CONFIG_LASI_82596=y and I changed the audio driver from ALSA to OSS.
As hppa-sources-2.6.11_pa2 are now in portage (and marked hppa stable) I emerged them and tried them out. The NIC now works with the latest kernel in portage, so I close this bug, setting it to FIXED.
