Hide Forgot
I am having serious kernel problems with hibernation on a Sharp PC-PJ2-X4 (a Japanese model similar to the Sharp Actius PC-A290 sold outside of Japan). I am sure that it is a kernel bug in 7.0, because I didn't have any problems with RedHat 6.x on the same system. When resuming the system from hibernation (save-to-disk), the system often (but not always) either immediately hangs or looses the ability to access the builtin IDE harddisk (and prints "hda: lost interrupt" to the console). Usually, this problem appears with a 20-30% chance; however, if I have used a PCMCIA card (ethernet or SCSI) before hibernation, the problem is guaranteed to occur. I have inspected and toyed around with the configuration under /etc/sysconfig/apmd, but this didn't seem to have any effect. The configuration of the machine is as follows: CPU: Mobile Pentium II Host bridge: Intel 440BX - 82443BX Host (no AGP) IDE interface: Intel 82371AB PIIX4 IDE (rev 1) hda: TOSHIBA MK1214GAP CardBus bridge: Ricoh RL5C475 rev 00 PCI-to-CardBus Kernel: 2.2.16-22 It has a Phoenix NoteBIOS.
I'm observing the same problem with a different machine and kernel. Ever since the 2.4.18 series was available from Rawhide I've seen this problem. Stock (and all updates to) 7.2 work fine. Since 7.3 comes with the 2.4.18, it has this problem. I'm running a Gateway 9300: # lspci 00:00.0 Host bridge: Intel Corp. 82815 815 Chipset Host Bridge and Memory Controller Hub (rev 11) 00:01.0 PCI bridge: Intel Corp. 82815 815 Chipset AGP Bridge (rev 11) 00:1e.0 PCI bridge: Intel Corp. 82801BAM/CAM PCI Bridge (rev 03) 00:1f.0 ISA bridge: Intel Corp. 82801BAM ISA Bridge (LPC) (rev 03) 00:1f.1 IDE interface: Intel Corp. 82801BAM IDE U100 (rev 03) 00:1f.2 USB Controller: Intel Corp. 82801BA/BAM USB (Hub (rev 03) 00:1f.3 SMBus: Intel Corp. 82801BA/BAM SMBus (rev 03) 00:1f.4 USB Controller: Intel Corp. 82801BA/BAM USB (Hub (rev 03) 01:00.0 VGA compatible controller: ATI Technologies Inc Rage Mobility M4 AGP 02:02.0 CardBus bridge: Texas Instruments PCI1420 02:02.1 CardBus bridge: Texas Instruments PCI1420 02:06.0 Communication controller: Lucent Microelectronics F-1156IV WinModem (V90, 56KFlex) (rev 01) 02:07.0 FireWire (IEEE 1394): Lucent Microelectronics FW323 (rev 04) 02:08.0 Multimedia audio controller: ESS Technology ES1988 Allegro-1 (rev 12) ide0: BM-DMA at 0x1800-0x1807, BIOS settings: hda:DMA, hdb:pio hda: TOSHIBA MK3017GAP, ATA DISK drive Ideas on this are appreciated. I'm likely to downgrade to the kernel from 7.2 so I can suspend and resume reliably. Thanks!
I may have found a workaround for my laptop. Looking at Bug#20658 I tried changing /etc/sysconfig/apmd to stop and restart PCMCIA services on suspend/resume. This appears to have changed the behavior. I have since been able to suspend/resume twice without the machine hanging on the HD. I'll need to try this with a different PCMCIA card (I switch between two) so more later...
Thats a BIOS problem not a Linux one so closed.
